Arsene Wenger's plans for tonight's crucial game at the Reebok have been hit by news that Sol Campbell and Thierry Henry are doubtful for the game.
Both players are reported to be struggling with hamstring injuries and Wenger may be unwilling to risk them.
Campbell's absence is not a huge problem as Martin Keown and Tony Adams will continue at the back. But the loss of Henry would be a blow.
Sylvain Wiltord is back in the squad and would probably deputise. Le Boss can also call upon Franny Jeffers and Kanu.
Bolton have a few injury worries of their own. Greek international Kostas Konstantinidis will probably continue to deputise for Mike Whitlow at the back. Paul Warhurst and Stig Tofting are out, but Riccardo Gardner (who was sent off in the 1-1 draw at Highbury earlier in the season) could shake off a hamstring problem to play.
Bolton boss Sam Allardyce has said that his team will give their all, but warned : "we canít go out and play attacking football against Arsenal."
The Trotters successfully avoided relegation from the top flight for the first time since 1979 thanks to Manchester United's 1-0 win at Ipswich on Saturday, and Allardyce said: "United have done us a favour, so it would be nice to repay them by getting a result against Arsenal."
