I can't think of a single thing Shane Long is bad at. He's quick, strong, he can shoot, he can cross, he can defend, he can sing...
He'd be a better lone striker than Pogrebnyak.
Strewth i'd be a better lone striker than the Pog, all the strengths you mention of Longy the Pog doesn't have ,although not sure about singing. Fraid to say think we've bought a turkey, and should break the bank to bring Longy and Sidwell back
