Arsenal’s bid to win the English Premier League title threatens to be derailed by a lengthening injury list with manager Arsene Wenger currently without nine first-team players.

Striker Robin van Persie (ankle) and Johan Djourou (knee) seem set to miss the rest of the season but there are a growing number of players at the Emirates who have shorter-term injury problems.

The latest feature midfielders Aaron Ramsey (thigh) and Samir Nasri (hamstring), who were both injured in training before Sunday’s 2-0 victory away to Bolton – a win that moved the Gunners to within three points of leaders and London rivals Chelsea.

Both Ramsey and Nasri are set to be out for three weeks each and will be among the Arsenal players missing from Wednesday’s hoem match against Bolton, where a victory would see the Gunners go top of the table on goal difference.
