Thibaut Courtois has failed to recover from an ankle injury in time for Chelsea's crunch Premier League clash against Manchester United, while the Red Devils have surprisingly benched Zlatan Ibrahimovic.
Belgium goalkeeper Courtois reportedly injured himself in training in the build-up to the match, which has added impetus for the league leaders after Tottenham cut the gap at the top to four points by battering Bournemouth on Saturday.
It is the first time this season that Courtois - who has been linked with a move to Real Madrid in the upcoming transfer window - has not started a Premier League fixture for Antonio Conte's side and means Asmir Begovic will deputise in his place at Old Trafford.
Chelsea were dealt a further blow when Marcos Alonso was injured in the pre-match warm-up, the Spaniard walking down the tunnel feeling the back of his left thigh, and was replaced in the starting line-up by Kurt Zouma.
