I actually think it could be a great signing, and does not require him to be a center forward to get the goals we are looking for.
When I look at our attacking options, obviously Suarez is the main man, will remain up top, but be allowed to roam wherever he can find space.
But then we have Sterling, who is willing to come inside, but is not yet a major goal threat; Downing, who looks more comfortable staying on the touch line swinging in dangerous balls; Suso who can play wide, but looks to me to be more of a second striker or play maker, and like Sterling has not yet looked like a real goal threat. Beyond that the other attacking options such as Shelvey, Gerrard or even Henderson are all attacking midfielders.
Sturridge to me looks much more like our forgotten (and written off by some) man Borini, but maybe stronger and already acclimatized to the prem style of playing; Players who may line up wide, and are expected to work the flanks and their respective channels, but will also interchange with each other and the main striker to be a real threat in the box.
