We need pace and power in the air, and on the ground.
Burnley for example, could have scored a few from crosses just in the first half. They did eventually get one from a cross in the second half.
The thing about defenders, is that they all make mistakes. The good ones, seem to cover it up, and also make attackers doubt themselves.
We need bit of everything: physical play, pace at the back, good aerial ability, and also a bit of nastiness.
Dunk/Tarkowski/Mee for one spot would be fine by me
Umtiti/Konate/Manolas for another spot
Although Konate seems to tick all boxes
