With us getting in Paulista and Coqs playing well, we really didn't have a major urgency to bring anyone new in. We are also playing well at the moment and appear to be getting better. We have enough cover for pretty much every department and bringing in someone new right now could be counter productive.
Also is Chuba a good signing? I haven't seen much of him but if he is of similar quality to Gnabry, then he is worth signing up. Though it's probably best he goes out on loan as he will see very little game time with us.
