Your point is a valid one, although I'm not sure he's good enough to be ahead of Son/Lamella/Dembele/Eriksen amongst others going for those three slots behind at the moment....Signing Berahino would potentially be a great move because he wont have to sit on the bench behind Kane. If we buy a traditional forward in the mould of Harry then we have two players going for one spot. If we buy Berahino he's versatility means he wont just fill in for Kane against lesser teams and through injuries, but both can be in the starting 11 at the same time.
