He's a bit of a ****. Although most of the best the strikers normally are. Chelsea getting Lukaku instead then? Seems a bit odd. In the short term, that's actually a backward step. Costa is a far more polished player than the big Belgian. For all the hype about Lukaku's power and aggression. His first touch doesn't match the levels of the best strikers yet. Which is why Chelsea offloaded him in the first place.
