I don't keep track of mine, but in terms of youngish players:Southend Worst Transfer-Outs XI
GK: Ederson Moraes [Arsenal]: From 88 to 92
I knew Ederson was going to become a class player and with having De Gea, there was no option other than to sell. Still amazed that only Wolves was interested in signing him at the time - and for cash.
RB: Joao Cancelo [Everton]: From 80 to 91
Yeah.
LB: Ben Davies [Aston Villa]: From 87 to 90
I've got quite a few LBs now so no regrets.
AM: Bernardo Silva [Everton]: From 91 to 92
A case where I had plenty of attackers, he wasn't playing much at City and I had the opportunity to bring in a top class CB prospect at the time in Christensen. Since then, the latter has become frozen out while Bernardo has gone from strength to strength and will rise to 93.
LM: Heung-Min Son [Southampton]: From 90 to 92
At the time I had 50 billion attackers and still have plenty. He'll rise to 93 but not got any regrets as such.
I'm sure there are plenty more, and Brahim Diaz and Mikel Merino will probably be added to the list.
