Eh, you've a fair point. I just can't see him working as the lone man with the current Chelsea set up. Sure, he's a powerful forward and has a decent finishing ability, but he isn't technically savvy enough to effectively play in front of the midfield Chelsea are fronting right now. Torres, while being largely a flop, has at least proven he can work in front of a technically gifted midfield and Ba is incredibly effective at holding up the ball, so if anything Ba is the best choice for the current Chelsea attacking force, if only to give the midfielders a good focal point as they get into more advanced positions.
