DCL had a few good games under Dyche but I doubt anyone is giving you any more than 15m for him with his injury record and years long prior record of being shite.
He wasn't and has never been shite. He has and was a young player growing into a role as a ST and had a trajectory of year by year improving his game and goals prior to injury. He has been good this season and has also had a full season with relatively little to no fitness concerns. Rumours are that Newcastle are interested if Isak goes (Wilson already looks like he's on his way out) and we can get between 20-30m for DCL if so. I think he's our most important player in this Dyche squad aside from Pickford. We can replace a Branthwaite or Onana, we would find it incredibly hard to replace what DCL does and is as a forward for our style.
