Said it in a reply above but unless Gueye goes I really think N'Zonzi would be an unnecessary signing. Didn't we spend the first portion of the season complaining about two DM's? Rather go for a more creative player that can dictate the play from deep. A midfielder such as Ozyakup from Besiktas, or someone of a similar mold since Arsenal look keen on him, would be a great addition.
Would rather sell gueye and sign nzonzi tbh. Would get 30m for gana I reckon and that should be enough to get nzonzi
