Keep all current strikers.
If we sell Tevez, which looks very likely, I say bring in David Villa.
Don't give me the "he's too old" nonsense. Just watch the man play, see how many runs he makes, how many opportunities he creates and how good of a finisher he still is.
He would work very well with our creative players. Would not cost too much in transfer-fee, and his reported too-high wage demands are likely negotiable.
Would love to see him get a real chance here with us, and it would not surprise me one bit if he turned out to be our leading scorer at the end of the season.
