Sorry to disappoint you and others in this forum section but Maxwell is doing a Dustin Fletcher, ONE season at a time and if his body is fine and he is enjoying it still, he'll play the next season. I know this for a fact.
On the captaincy front, Maxwell is still captain HOWEVER he has suggested to the club that he can be a leader without the title to help the younger guys coming through. Who knows, Maxwell may just play another 2-3 seasons including this season. BUT if the players still want him as captain, he'll keep going.
How do I know this? He told me personally. He just left our house after visiting my mum who is very ill.
I hope you mum gets better soon mate.
