Arsenal striker Robin van Persie's knee injury threatens to rule him out of their trip to Barcelona.
The Daily Mail says Van Persie is a serious doubt for Arsenal's Champions League clash against Barcelona next Tuesday.
And the Gunners have suffered a second blow after their Carling Cup defeat by Birmingham as it emerged that Thomas Vermaelen will not be fit enough to make his long-awaited comeback for the reserves against West Ham on Tuesday.
Van Persie, 27, injured his right knee in scoring his 13th goal in 11 games this year in Arsenal's 2-1 loss on Sunday.
The Gunners' medical team will continue to assess the Dutchman today but he faces a real battle to be fit for next week's trip to Spain.
