Shinji Kagawa, Manchester United's Japan international midfielder, faces at least another four weeks out of action according to manager Sir Alex Ferguson.
Kagawa has been sidelined since suffering a knee injury against Braga in the UEFA Champions League at Old Trafford last month.
Initially, Ferguson said he thought Kagawa would be back playing within four or five weeks. But, speaking ahead of Tuesday's Champions League match away to Galatasaray in Istanbul, Ferguson told United's website: "Shinji's progress has been quite slow actually.
"He's not started any outside work and we're looking at another four weeks, which is disappointing. Originally we thought three or four weeks - now it looks like seven or eight weeks," the veteran Scottish manager added.
It was disappointing news for the 23-year-old Kagawa, who has impressed with two goals in his first eight appearances since a £12million ($19million) pre-season move from German club Borussia Dortmund.
