I guess your right but it comes down to risk/reward, we have witnessed a 50million flop already and doing so again is another huge risk but it could go well for us. If we did sign Cavani, I'm sure Lukaku would get as many chances (I know you're worried about him not playing if this deal goes through), because technically we could play all our strikers on the pitch Ba on the left, Lukaku up front and Cavani on the right (theoretically). Cavani is quite versatile and is used to playing off other players, behind the main man and out wide. This is why Lukaku would probs get at least 25/30 games to see how he gets on in a blue shirt.
