Sir Alex Ferguson admits he does not know what the best strike partnership is at Manchester United.
Wayne Rooney's return from a gashed thigh in Wednesday's Capital One cup win over Newcastle means Ferguson could start his perceived first-choice pairing against Tottenham on Saturday.
Rooney and Robin van Persie is the strike force many are anticipating but with Shinji Kagawa able to operate off the frontman and Javier Hernandez and Danny Welbeck looking for a chance, Ferguson has options.
Thirteen years ago United won the treble with a quartet of Andy Cole, Dwight Yorke, Teddy Sheringham and Ole Gunnar Solskjaer and that is the sort of competition the United boss is seeking.
"It is early doors but at the moment I don't know where I am going in the sense of what my best partnership will be," said Ferguson.
"Probably the strongest part of the club will be in the striker department. It (Van Persie's arrival) should give everyone a push.
"Danny Welbeck is in the same position as Javier in that they are not the first team choices at the moment.
"That doesn't mean to say it will stay that way because competition is always healthy and them being the kind of young lads they are will be desperate to establish themselves.
"That is what competition is. We had it in 1999."
