I think holding up the ball and something to aim for in the box is what we've been missing with Aluko and Koren, when I say something to aim for in the box I don't mean simply to his head as its clear to see that's not his strong point. However he makes runs when in the box unlike Simpson who I do like but he's simply ****e in the box. We saw it against Ipswich, Proschwitz the first goal was a near post tap in, a run to the near post is what we've been needing from Elmo's balls in.
I don't think its guaranteed we will sign a striker, however if it is, it will be a striker who can play Premier League football also.
