Costa is similar to Suarez in that he's a bit of a **** -he wont go as far as to bite people, though- and he's got terrific workrate, but he's not as quick or as tricky as the uruguayan, although he's certainly stronger and has a better eye for goal. I follow Rayo Vallecano in La Liga and the season before last he had a terrific 6 months -and that was after tearing his ACL- with them alongside Michu, and the way he played for Atlético Madrid this season suggests it's not a one-off. I'd consider it a coup for Liverpool if they managed to sign him, in all honesty.
