I'd definitely be looking to keep Brereton offer him a new contract 2 years with a rise on the promise that of someone comes in next summer he can go, I genuinely believe he will kick on next season too, yeah his goals dried up in second half of the season but I think he brings much more to the team than just goals, he commits defenders he also has a really good football brain and wins free kicks in dangerous positions.
Even when people wanted rid of him the season before I thought he had a decent season and definitely had talent just lacked confidence. I think if he got a move to a prem club I think he'll excel I genuinely do. So for me try our best to keep him if he doesn't want to stay fair enough cash in but I think in 2/3 years we'll be looking at a good Premier league player.
