I've come back round to the idea that we don't actually need to sign a left back; particularly with the way we are currently lining up with a three at the back when in possession or when the ball is in the opposing half, which is so much of the time.
In those circumstances, we have Zin, Mendy, Laporte, Ake and Cancelo who can play "LB".
Mendy is better than many give credit for, even if he is the weakest link in the squad - a squad that may be the best ever assembled by a club.
We can go again next year with our current set of defenders.
