Who would buy him mate. ? He's on over £100k pw by all accounts. I don't think any of the top 6 clubs will buy him, not unless he get's back to top form consistently and then he won't be for sale. Leicester, Wolves or West Ham aren't forking out those wages plus a transfer fee unless his form improves, and even then not even sure he'll go. Possibly a big name Italian team like Milan or Roma will take him on loan for a season, and if he does well then maybe buy him. But that's our best chance. IMO.
For me, he'll either play himself back into form, in which case we keep him, or he doesn't and he ends up going out on loan each year with us covering part of his wages. Hopefully he get's his form and confidence back as an in form Gomes is a key member of our squad.
