Graeme Le Saux is absent with a hamstring problem while the midfield trio of Matt Oakley (knee), Chris Marsden (hip) and Gavin McCann (ankle) were also left behind when the squad travelled to Romania yesterday.
While Strachan acknowledges the dilemma, 25-year-old Beattie sees a chance to press his way into England's squad fornext summer's European Championship Finals in Portugal.
He added: 'Mr Eriksson has made it public that if you're scoring in Europe you will be noticed. Obviously the Champions League is the place to do that, playing against the best players in Europe. But the UEFA Cup's not too bad, is it?
'I can always see us scoring with so many attack-minded players in the side and myself and Kevin in there. Steaua need to go forward more than they did at St Mary's, which may give us more space. We have to score, I know that.'
