Donovan is no striker. He will do no better at that role than Cahill. Donovan is a winger. I am so confused as to why so many people on this forum want to play him as a forward/striker. The solution to our problem is as someone stated earlier, if you want Cahill to play better we need Velios in to hold the line.
Doesnt really matter , Cahill is not a striker , both him and Donovan are goalscorers and at the moment Cahill has not been scoring goals , Donovan has . Its a trait of players that Moyes signs , they have to be adaptable and versatile and If Moyes thinks he can do a better job than Tim C then he'll use him in that role
