Manchester City midfielder Kevin De Bruyne has announced he faces 10 weeks out of action after damaging his knee and ankle against Everton.
The Belgian suffered his injury setback late in the Capital One Cup semi-final win over Everton on Wednesday, having come off the bench during the second half and changed the game with a goal and an assist.
His efforts helped to set up a trip to Wembley for City next month, when Liverpool await them, but cruelly De Bruyne is set to miss that occasion along with important Champions League, Premier League and FA Cup games.
De Bruyne wrote on Twitter: "Just got back from the specialist. I'll be out for around 10 weeks.
"I'll work hard on my recovery and hope to be back on the pitch asap. Thank you all for the supportive messages!"

City won the second leg 3-1 to take the tie 4-3 on aggregate, with De Bruyne's appearance ending when the 24-year-old appeared to get his studs caught in the turf and then landed on his knee.
He stands to miss both legs of City's Champions League last-16 clash with Dynamo Kiev, the Wembley clash with Liverpool on 28 February and the Premier League derby against Manchester United on 20 March.
If the 10-week forecast proves accurate, De Bruyne should be back in contention to feature against his former club Chelsea on 16 April.
He should also be back in time to play enough football to assure Belgium of his fitness ahead of their Euro 2016 campaign.
De Bruyne's representative Patrick De Koster told Sky Sports News: "Kevin is sad. His dream is to always be playing football. He will miss games like the League Cup final and in the Champions League, which are important.
"But he knows they (City) are a good team, that the other players will do what they have to do, and maybe win the game for him, and also that (injuries) is what happens in football."
De Koster detailed the injuries as a "tear in the ankle and also the lateral (knee) ligaments".
Everton goalkeeper Joel Robles apologised to De Bruyne after the game for attempting to pick the player up as he lay down in pain.
The Toffees, though, remain incensed about the manner of their defeat, with Everton captain Phil Jagielka labelling referee Martin Atkinson "a little bit arrogant" in his attitude.
Jagielka was unhappy with the response he got when he asked Atkinson why a critical City goal, scored by De Bruyne after Raheem Sterling ran the ball out of play, was allowed to stand.
Atkinson and his officials missed the ball crossing the byline before Sterling pulled it back for De Bruyne to put City 2-1 ahead at the Etihad Stadium.
Asked if he spoke to the referee, Jagielka said: "I tried to. He told me that my defending was brilliant.
So, it is difficult when things start going the wrong way and they become a little bit arrogant - but unfortunately that is the way it goes with some.
"If he made a decision wrong or he didn't see it, that is what happens, but sometimes when you go and speak to people and, in such a big game, get the answers you get it is that little bit more frustrating."
Sterling may get a rough ride from Liverpool fans in the final but he is not concerned.
He said: "That is not a big thing on my mind. Obviously it is my ex-team, but it is just another team on the way to get past.
"It (the final) is in my home city and it is something I have wanted to do since I was a kid. Nothing is going to stop me from doing it."
