He might be good for Arsenal but he need to leave Barca. He has had enough chances more than any of our "young" midfielders. He never impressed even Rafinha was good at some point. Just sell him for whatever we can. Denis will be still there in case of any injuries and Arthur is coming.
Absolutely no idea how this guy is still at Barca. Paulinho was way more useful than him and we got rid of him after 1 season. At least we got our money back.
Gomes is with us for the entirety of his contract it seems, no team wants him. I'd take 10 mil for him at this point just to recoup anything at all.
