i dont think we need so many strikers, especially if trez is leaving. the only reason why we need a second back up if to cover trez for his injuries each season.
im liking the crespo and huntelaar rumour, that would be ideal.
as for zalayeta, he may be a good sub, but not for the right reason. he accepts the bench, never complains and that's great to have..but is isnt a super sub who can come on score when you ned it. sure he scored twice last game, but we need someone who is more prolific (yes in the CL semi finals and quarter finals in the past he has scored crucial goals, but i think everyone gets my drift)
Another aspect to think about is what tactics DD will play. if he is going to introduce a 3 pronged attack...then players like Marchionni and Nedved can be used in advanced roles as well.
4 forwards overall should be enough considering we dont play in the CL.
