Thomas Tuchel will aim to give Chelsea a virtual team-talk ahead of their Club World Cup semi-final on Wednesday.

The Blues boss has been unable to join the Blues in Abu Dhabi after testing positive for coronavirus.

The German missed Saturday's 2-1 FA Cup fourth-round win over Plymouth, watching from home as his side edged out the Pilgrims after extra time.

Tuchel’s assistants Arno Michels and Zsolt Low will take charge for Wednesday’s Club World Cup semi-final against Al Hilal at the Mohammed Bin Zayed Stadium, but will be in constant contact with Tuchel.

And the former Borussia Dortmund boss will do his best to deliver a pre-match speech through video technology.

"We’re constantly in contact with Thomas," first-team coach Low said. "We have a lot of meetings together and we’re video calling all the time, many times in the day.

"We record training and send that to him, we change ideas a lot of times in the day.

"It’s a question for the next hours and the next day, maybe, as to how we can connect Thomas with the team before the match.

"I think in the hotel it might be easier; it might be more difficult at the stadium.

"But also during the game we can be in contact with him, on what he sees and what he wants us to do."

Chelsea remain hopeful Tuchel will be able to join the Blues in the United Arab Emirates for Saturday’s match, which will either be the final or the third-place play-off.

Low insisted none of Chelsea’s other coaches will attempt to mimic Tuchel’s passionate and energetic touchline demeanour in Wednesday’s last-four encounter.

"You can’t copy Thomas – he’s one of the best coaches in the whole world," Low said.

"That’s why you have to share the training and coaching, and do different roles.

"And on the sideline also, as in the cup game we’ll swap over between myself and my colleague Arno Michels, to try to push the team forward.

"And change all the time if somebody sees something or has a good opinion they can communicate it during the game or at half-time."

Edouard Mendy was named Goalkeeper of the Tournament at the Africa Cup of Nations

Goalkeeper Edouard Mendy is also yet to link up with Chelsea, having claimed Africa Cup of Nations glory as Senegal overcame Egypt to lift the title.

Chelsea assistant Low has not ruled out Mendy playing a role on Wednesday, but that appears remote at this stage.

Mendy will arrive in Abu Dhabi on either Tuesday or Wednesday, with Chelsea waiting until then to make a final decision on the starting goalkeeping berth.

The likelihood remains that Kepa Arrizabalaga will start, especially after the Spain stopper’s dramatic penalty save in extra time that sealed Chelsea’s edgy win over League One Plymouth at the weekend.

"Mendy should be travelling later (on Tuesday) or (Wednesday)," Low said.

"So we’ll see how tired he is. He has to arrive first and then we’ll check him.

"And so then we’ll see if there’s a possibility that he plays.

"It’s a good situation for the coaches, with two amazing goalkeepers in Kepa and Edouard. Then we have to decide who will play.

"Mendy has had a fantastic performance to win the Africa Cup of Nations.

"And Kepa has done an amazing job, with the penalty save at the weekend so he’s also in very, very good shape.

"When Mendy arrives, we’ll see what decision to make."

Cesar Azpilicueta has won every club trophy available except the Club World Cup

Cesar Azpilicueta has told Chelsea to go and make history by claiming a maiden Club World Cup title in Abu Dhabi.

Chelsea can break new ground by lifting the Club World Cup crown this week, and victory would complete Azpilicueta's trophy clean sweep at club level.

The Blues skipper has tasted success in every other major club competition, and now wants to complete the set.

Azpilicueta was among Chelsea’s unsuccessful 2012 Club World Cup tilt, and has warned his team-mates just how tough a task faces Thomas Tuchel’s side in the United Arab Emirates.

"It is very difficult to win this kind of tournament," said Azpilicueta.

"I think after 10 years I realise how difficult it is. We lost the final against Corinthians (in 2012) and maybe I had a different feeling.

"It was my first season, we were in every competition, and maybe it looked easier than it was.

"In time you realise how difficult it is. First of all you have to qualify for the Champions League, then go all the way and win that, just to be here. So we have to make the most of it.

"Losing in 2012 hurt a lot and this is the only competition the club hasn’t won. To win it for the first time for the club would be huge. We have to give everything we have on the pitch. It has great meaning for everybody, and we are representing Europe."

The 32-year-old is out of contract in the summer and might just be entering the business end of a season with Chelsea for the final time, with the likes of Barcelona heavily interested in his services.

The Stamford Bridge skipper has rejected any personal concerns however, with his focus fully on securing yet more glory for the 2021 Champions League winners.

"My future is not the most important thing right now, my main target is to win the trophy and then we will see what happens with my future," said Azpilicueta.

"I think everyone is trying to create their own history within the history of the club.

"Through the years we’ve seen many, many world-class players, managers and everybody at the club try to help increase the trophy cabinet of this club.

"And we are part of that now. So when the time arrives you want to make the most of it.

"It’s true we have our own opportunity to create history and to win a trophy nobody has won at Chelsea. Hopefully we’ll be the ones to do it."
