Sam Allardyce: "He has shown everybody what he can do and he has massive potential to grow into a very good player if he ends up back here with us.
"He's so willing to learn and become better that I think we could do well for each other, but there is a way to go before that might get sorted.
"It's about negotiation and both parties have to be happy that the negotiation cannot go any farther and it's a 'yes' or 'no'. We hope it's a 'yes' and we hope it is as quickly as possible.
"I think that my reflection of Andy is exactly what I said from the start - as soon as we get him match-fit, the sooner you will see the goals.
"That match-fitness never came until his run after his second injury and I'm still wondering what he might have done this year had we got him off that one minute before he did his hamstring in his first game (against Fulham)."
