Robin van Persie will miss Manchester United's Capital One Cup third round clash against Liverpool, according to David Moyes.
The United striker missed Sunday's 4-1 Manchester derby defeat to Manchester City with a groin injury - and last season's Premier League top scorer has not yet recovered.
However, Moyes revealed that Van Persie has an "outside chance" of starting Saturday's league clash against West Brom at Old Trafford.
The Red Devils' manager is under pressure to beat Liverpool on Wednesday night following Sunday's 4-1 loss, which "shocked" the former Everton boss.
United were outclassed by the local rivals at the Etihad Stadium and only managed to salvage a little pride thanks to Wayne Rooney's sumptuous second-half free-kick.
Moyes insists that he is still "getting to know his players" - and it's believed that he will offer those on the fringes of the first team a chance to stake their claim against Brendan Rodgers' side this week.
