It's got to either be him or Mitrovic, and he just gives the same issues. Although he'd took his chances well in pre season and in his cameos so far. Gayle would have scored the second, but I doubt he have got on to the first, or have been able to take the third on his chest and get into the box like Joselu did.
We need one of the two big lads up front because they make us a better team all round.
