Manchester United are still struggling defensively before their home game against Everton on Saturday with Rio Ferdinand and Fabio definitely out injured, Jonny Evans and John O'Shea doubtful and Gary Neville suspended.
Manager Alex Ferguson said on Friday that Ferdinand's long-running back problem had finally been identified but that he would still be out for a couple of weeks.
"The lads that have been in the team have been fantastic but we need that bit of extra help," Australia midfielder Tim Cahill said. "It's about how we kick on and get more injured players back to share the workload."
Arsenal will be without Robin van Persie (ankle) and Kieran Gibbs (foot) for Saturday's trip to Sunderland after both picked up injuries on international duty.
Manchester City manager Mark Hughes will have midfielder Gareth Barry available for Saturday's trip to Liverpool, while 23-year old defender Nedum Onuoha is nearing fitness.
Tottenham Hotspur's England winger Aaron Lennon has recovered from the ankle injury he picked up last month and is ready to return at home to Wigan Athletic on Sunday.
