Following our imminent signing of schneiderlin for what it's worth Ill tell you what I think we now need to take us up to current top 6 level.
A new goalkeeper, someone like Leno would be fine, I feel we just need a top level keeper.
A new centre back. A commanding tall and strong centre back. Had Jose fonte not been the wrong side of 30 I would suggest him as I think he's very impressive. However van dijk would be my top choice. I've not seen enough of keane to comment but not 100% sure he would be of the required level. Another one is manolas, he would also be perfect.
A top creative midfielder. This player is the key I think. He can make the likes of mirallas, deulofeu, Lennon all take their game up a level. They have missed the right service and it's due to a lack of a decent creative player in the team. the big problem is there is a lack of them available. A modern arteta would fit in our team perfectly at the expense of barkley, however barkley would still have a large part to play as more of a squad player.
A new winger, we do need to cover the void left by bolasie. Could lookman be the answer? I'm sceptical about depay but he may be the best option when looking at what's available.
A new striker. We need serious competition for lukaku. He would need to be someone who could lead the line in the event of lukaku getting injured but also could partner him when necessary. Gabbiadinis name is still being thrown about and he could be the best option if available.
