Well to be fair, if you haven't watched the U21's like we have, and seen some terrible Blackett performances like we have, you'd probably think he was a very level-headed, calm player based off his time on the pre-season tour and in the first team. That's what I really don't get - aside from the Leicester game, I was impressed with Blackett's performances in the senior squad, but they were nothing like the sort that he put in regularly at lower levels. I've never really rated him, he has all the physical attributes and is good with the ball, but he's shown in the U21's that he's simply not good at defending.
I've not seen any U21 games this year mind, so maybe he's improved his game there, but in the last 3 seasons or so when I've watched the U21's he's never looked like a player who'll make it here. Especially when you consider our U18 prospects - Tuanzebe, Fosu-Mensah, CBJ and RoShaun Williams.
