Fergie's Selection Puzzle.

Football matches are won by scoring goals.

But the battle is often won in midfield, and that is cause for concern in the Manchester United camp.

An injury crisis has left Sir Alex Ferguson, usually spoiled for riches, picking through a threadbare central unit available for United's trip to Molineux.

That's not to say he still doesn't have options.

But they may not be ones he particularly likes.

Richie Jones has been recalled from Antwerp such is the worry currently felt at Old Trafford.

And there are other positional changes being considered that could alter United's game.

Wayne Rooney is a thorn in every teams side. As a forward he can be deadly. A true matchwinner and a prodigy with the ball.

But how influential is he as a central midfielder? A selection choice being considered by his manager.

Rio Ferdinand is another who could see his role change.

Against Blackburn on Wednesday he came on late to bolster the midfield. Its thought that Ferguson may deploy him in a holding role on Sunday, sitting just in front of a back four that has looked shaky at times with him in it.

Taken out it is hardly likely to be strengthened.

Ferguson may choose to start new signing Nemanja Vidic in defence. Which will bring a smile to Tomasz Frankowski should he play.

When Poland last played Serbia and Montenegro Vidic marked Wolves new striker, and Frankowski managed to find the net twice.

Whatever side Fergie sends out, they will be well drilled, well trained, and well briefed.

But it still wont be anything close to their first choice. And that is bound to give Wanderers a boost.
