Premier League champions Manchester United are expected to be without their most influential midfielder, Michael Carrick, until Christmas.
The 32-year-old withdrew from the England squad on Tuesday ahead of the forthcoming England friendlies against Chile and Germany with an Achilles problem - and reports claim he is now expected to miss the next six weeks after undergoing a procedure to resolve the injury.
Carrick played the entire 90 minutes against Arsenal on Sunday, but complained of discomfort after the final whistle.
"I have been carrying the injury for a few weeks now," he told reporters. "I was a bit patched up to play. I got through it but it doesn't look too good."
Carrick is now likely to miss United's forthcoming fixtures against Cardiff City, Tottenham, Everton, Newcastle United, Aston Villa and West Ham - as well as the Red Devils' remaining Champions League matches against Bayer Leverkusen and Shakhtar Donetsk.
United boss David Moyes will hope to get the most out of £27.5m summer signing Marouane Fellaini in Carrick's absence.
The Belgium international has endured a difficult start to the his Manchester United career, but will now have the opportunity to endear himself to the club's supporters.
