I really like Tav, and would be sad to see him go but he can be so frustrating to watch some times. He clearly has the talent, just wish he wasnt so wasteful with some of the chances he's had this season. But I think the club had one eye on him leaving, that's why in my opinion Mcgree was signed, as competition/replacement for Tav.
Dael also on his day he is definitely one of the best defender in the league but like Wilder said he needs to be more dominant, that will come with age I reckon. But he isn't irreplaceable, there are a few good CBs around which we could replace him with
