Manchester City are in fits of sweat regarding the fitness of influential captain Vincent Kompany after the centre-back limped out of training ahead of a potential Premier League title decider against Liverpool.
The Belgian had a heavy fall after an aerial duel, and could not play a further part in the session after being carried off by concerned teammates, according to various sources.
He is now a doubt for the trip to Anfield, and if Kompany cannot take his place in the starting XI tomorrow against Liverpool it could seriously harm his side's title chances.
The 28-year-old is one of the Citizen's leading players and he was expected to lead the defence against the Reds' lethal strike duo of Luis Suarez and Daniel Sturridge.
Suarez and Sturridge are the Premier League's two highest goalscorers and have notched a hugely impressive 49 goals between them.
Kompany is the only mainstay at the heart of Manuel Pellegrini's defence and tomorrow's visitors might have to rely on the error prone Martin Demichelis to keep the potent pairing out.
Sunday's clash is one of the most eagerly anticipated that the top-flight has seen for quite some time.
Brendan Rodgers' men can win a first Premier League title if they pick up maximum points from all their remaining games but a City win would put them in poll position to replicate the success they tasted two seasons ago under Roberto Mancini.
Chelsea are also sandwiched between the duo as we approach a fabulous finale to the season.
Kompany came to England from Hamburger SV back in 2008 and has proved to be a massive hit at the Etihad Stadium.
The powerful centre-back skipper City in their first title win as mentioned before and has made over 200 appearances in total.
