I did a statistical comparison between 5 of our linked LBsFabinho and Mendy will cost a fortune. They are on long terms contracts so no need for Monaco to sell at anything below 40-50 GBP million at least....
Mendy, Sandro, Rose, Bernat, and Hector. Of the 5, statistically, Mendy was the poorest. He had a high attacking score (a function of having 11 assists I suppose), but his possession. And defensive scores were poor compared to the others.
And when you go deeper into the offensive category, I also noticed he was creating fewer opportunities than say Bernat, Sandro or Rose par game. It just so happen his teammates are more clinical finishing off those chances.
For what its worth, I'd have all 4 Grimaldo, and Theo over him. I simply don't find any defender at Monaco convincing. They are all deeply flawed.
