I think we need a striker, wether that be a loan signing like Lukaku or get him in a swap for Felli or we sign someone like Cornelius, Finnbogason, Wilfried Bony or Negredo?!.
But i think if Felli does leave this summer, we need to replace him with a Coutinho type player IMO. We need someone who can create centrally and pick out and play the kind of through balls that he does that strikers with good movement and like to play on the shoulder thrive on!.
I do feel we are too reliant on our wide play and more often than not do try at every opportunity to work the ball wide, mainly down the left, to create our chances but it would be nice to have some creativity in central areas.
Playing Felli up there behind a striker can work and he does well but he basically plays like a target man up there and when we go long, he brings the ball down and brings the midfield into play or he lays it out wide, which isnt a bad thing, but he's not a player to control the ball, turn on it and look to feed the striker.
This summer we do need a striker to add to ranks but i think some creativity in the centre of midfield, especially in the role behind the front man, we do need a clever, creative type player but i think we can only do all those things, buy a striker and a midfielder, if we sell Felli.
