PREVIEW: Celtic (SCO) v Ajax (NED)

Successive defeats have left Celtic three points adrift of the Turks with Ajax just one point better off and a draw would see both sides eliminated if Fenerbahce beat already-qualified Molde.

Celtic have gone nine games in this competition without a win -- three short of the record -- and defender Dedryck Boyata knows there's no more margin for error.

"It's a really important game. Our last two games in (Europe) were disappointing...we didn't manage to be as good as we usually are. (Now) we need to be at our best."
