Well, our GK and defence is okay, as Martinez won't upgrade Robles, Hibbert or Alcaraz. Our defensive part of midfield is okay... And then, wel... I hope we can loan in Traore as a second option for Lukaku, he would be just a perfect option and I would really hope we could buy him in the next summer for an agreed price in that loan deal, if it works well. If we can loan in Atsu, he would be a perfect replacement for Deulofeu IMO, an agreed price for him would be great as well, Chelsea don't need him in the long-term, he could do well for us. But even then I would still think we need one extra attacking player.
Pienaar can be that replacement for Barkley, in our current system, he is better suited to play there than on a wing, and so I think we need a boss winger. My dream signing would be Yevhen Konoplyanka, his buy-out clause is £12m and if no better club than West Ham will go in for him, he will likely sign for them. He would be an absolute bargain IMO, and as a big bonus, fans of our neighbours would be in a total meltdown. We still should have money available for these deals, if not, then please fund it by selling of Naismith, his value has to be really high if players like Borini or McCormack are going for deals above £10m.
