After getting to a World Cup semi-final in 2018, English fans will again dare to dream that they can end a 55-year wait for a major tournament, but their conquerors from three years ago, Croatia, bitter rivals Scotland and an improving Czech Republic, should ensure that Group D is competitive.
Manager: Gareth Southgate
Captain: Harry Kane
Player to watch: Jadon Sancho
Best European Championship performance: Semi-finalists 1996

After trimming an extended squad of 33 down to the required 26, Gareth Southgate did, after much speculation, make room for Trent Alexander-Arnold, so allowing for four provisional right-backs in his selection.
A further debate ensued as to whether TAA would be deployed in a more advanced role if he did see action in the next few weeks. That's all redundant talk after the Liverpool player picked up a thigh injury in the friendly against Austria, so ending his involvement in this tournament. Brighton's Ben White take his place.
Jesse Lingard, James Ward-Prowse and Ollie Watkins were among those not to make the cut, while Danny Ings and Patrick Bamford didn't even make the provisional squad.
Borussia Dortmund's Jude Bellingham, at 17, is there after some decent showings in the Champions League. His Dortmund team-mate, Jadon Sancho, finished the Bundesliga strongly and, along with Phil Foden, Mason Mount and Reece James, the manager is placing a well-justified trust in youth. It's well justified, with Mount outstanding for Chelsea in their Champions League win.
Of the experienced brigade, doubts persist over the fitness of Harry Maguire and Jordan Henderson.
In attack, Harry Kane is the favourite to be the tournament's top scorer. Jack Grealish, another player who could be part of a part of big-money summer move, now has the shop window to really showcase his talents.
He played the last few games of the Premier League season for Aston Villa, so allaying any injury concerns, and the considered view of some is that he and Phil Foden will be the providers of the ammo to aid Harry Kane to find the net.
England will be favoured to top the section and with it a likely date with either France, Portugal or Germany in the last-16. Win that and things could really open up. Playing all but one of their games away from Wembley will no doubt aid the Three Lions if they are to be the last team standing on 11 July.

From the high of reaching the World Cup final in 2018, Croatia, perhaps, not surprisingly, have enjoyed mixed fortunes since, with two wins from their last eight internationals giving some cause for concern.
The 2018-19 Nations League had them bottom of a group, involving England and Spain.
The subsequent competition saw Dalic's side take just three points from a maximum 18 in a section that contained France, Portugal and Sweden. Croatia did, however, top their Euro qualifying group.
Luka Modric remains the key man for Croats, particularly so after the retirements last autumn of Ivan Rakitic, Mario Mandzukic and goalkeeper Danijel Subasic.
Dinamo Zagreb's Dominik Livakovic is now the new man between the posts, with CSKA Moscow and former Everton midfielder Nikola Vlasic, the Dinamo's Zagreb duo of Mislav Orsic and Bruno Petkovic, and Hoffenheim's Andrej Kramaric, all steeping up as Croatia look to build something new.
Absent from the squad is Stuttgart defender Borna Sosa. The 23-year-old, who is on Leeds United's radar, put recent injury woes aside to show his full potential in the Bundesliga season just past.
Sosa holds Croatian and German citizenship and after not receiving a call-up from Zlatko Dalic for a World Cup qualifier in March, Sosa then caught the attention of Joachim Löw. However, FIFA regulations showed that the player was not in fact eligible to play for the Germans. Despite that door closing, Dalic did not include the player in his squad of 26.
Croatia should be good enough to emerge from the group. Six of the side that started the World Cup final in Moscow remain, with those stepping up key in helping the side being more than just dark horses at a major tournament.
Following on from the decision of the Czech Republic not to base themselves in Scotland owing to Covid restrictions, the Croatian Football Federation (HNS) says it will now not be moving into its proposed team camp in St Andrews. The squad will instead remain in the city of Rovinj, where they have already been training at the NK Rovinj Stadium.
Manager: Steve Clarke
Captain: Andy Robertson
Star man: John McGinn

For the first time since 1998 the Scots are part of a major tournament. That was the World Cup in France and two years before that saw their last Euros experience. They failed to get out of a group that contained England, Switzerland and the Netherlands.
Progression beyond the initial stage is easier now and with two games at Hampden Park, Scotland's loyal fans will be disappointed if they are not involved come the last weekend of June.
Goalkeeper David Marshall was the hero, saving Aleksandar Mitrovic's penalty, as Scotland got the better of Serbia in a dramatic penalty shoot-out win last November to seal their finals berth.
Manager Steve Clarke's reward for getting them this far is a likely extension to his contract beyond the World Cup qualifiers. His squad of comprising of regulars like Andy Robertson, John McGinn, Scott McTominay and Kieran Tierney also sees the uncapped trio of Billy Gilmour, Nathan Patterson and David Turnbull involved.
Southampton forward Che Adams only declared himself to the national team in March and immediately made an impact with a goal and an assist from his first two starts.
Aston Villa's McGinn scored seven goals in qualifying, a force that drives the Scots forward. Much more involved in the opposition penalty area than with his club. Celtic's Ryan Christie will also look to be among the goals. Defensively, there is some concern at the 19 goals conceded in qualifying and much work has been to tighten things up.
An opening encounter against the Czechs almost feels like a must-win. A defeat will drain confidence ahead of the trip south to Wembley and the havoc the England front line may cause. Still, two games in front of the Tartan Army at Hampden will aid their quest to reach the last-16.
Country: Czech Republic
Manager: Jaroslav Šilhavý
Captain: Vladimír Darida
Star man: Tomas Soucek

Twenty-five years after reaching the final, the Czechs are again daring to dream that they again can cause a stir on English soil. Qualifying saw a win over Gareth Southgate's side and both countries will face off in the concluding group game at Wembley.
There's an air positivity emanating from the Czech camp; the majority of the squad play in Europe's top five league leagues and an infusion of youthful exuberance has them down as a team who could ruffle a feather or two in the next few weeks. Last autumn saw Šilhavý's troops get promoted to the top tier of the Nations League.
Midfielder Tomas Soucek, dubbed the Czech Fellaini because of his aerial prowess, was to the fore in helping West Ham achieve as lofty Premier League finish, as was defender Vladimir Coufal. Burnley attacker Matej Vydra is also in the squad. Expected to lead the line will be Bayer Leverkusen's Patrik Schick, who is just as imposing as Soucek.
Tomas Vaclik, following in the shoes of Petr Cech, is a solid shot-stopper who has won the Europa League with Sevilla.
Due to the Covid-19 restrictions and rules in Scotland, the Czech squad will now base itself in Prague for the duration of the tournament, travelling to and from the UK for each of their matches. They had been due to set up camp at the Oriam national performance centre in Edinburgh.
The Czechs no doubt be targeting points their opening two games, imbued with a firm belief that they can progress.
