If he's coming in, which is pretty much a certainty, our technical level has just taken a leap. We've now got a consummate centre-forward who will play others in all day and occupy two centre-backs all by himself.
Martial and a speedy, tricky RW either side of him and a proper converter of chances behind, and we're going to be incredibly potent as an attacking force.
The CL is irrelevant to us, so Ibra's record in it is redundant. In the here-and-now, he is a huge signing, pivotal, in fact. It's up to us to supplement the attack and midfield to optimise both his game and the rest as a collective.
Rooney in behind him isn't a problem as long as the flanks, at both points (FB and WF), have pace to burn. Shaw, Martial, other and other on the other side has the hallmarks of a scintillating attack.
