The Celtic boss has already seen Danish midfielder Thomas Gravesen definitely ruled out while Jan Vennegoor of Hesselink, Aiden McGeady, Maciej Zurawski and Craig Beattie could all join him on the sidelines. A defiant Strachan said: 'I can't worry about it. Sometimes you can find a gem out of someone being injured, that's the way I look at it.
'I'm apprehensive before every game but not scared of losing players. Other clubs have maybe three or four very important players and if they're missing then it's a problem but I think I've got more important players here.' Celtic, currently riding high in the Scottish Premier League, will be looking to safeguard their second spot in group F tonight.
'We have a lot of confidence to win because we have a conviction in the way we play. Victory gives us more and more confidence,' he said. 'I have no doubt that we can win.
We are good enough. To win we have to defend well and attack with confidence, we will go for goals. We have to work very hard as a team.
'Celtic have good attackers and play an attacking game with two very good midfielders, but Benfica also have an offensive strategy.
