This deserves a bump up . . .
I've got a DC who is in his mid-30s \, solid technical skills, outstanding mental abilities, but has admittedly lost a step or two. Now, Assio Manio, just after promotion to the Championship says signing oldguycentreback wouldn't be worthwhile (forgetting I guess, that we had no one else who was worthwhile either). The guy does nothing less than lead the team in appearances and avg. rating.
Not liking the squad assessments this holio was giving me I sacked and got a better one (this poor bugger thought we would have no chance of avoiding relegation in 1) league 1 and 2) Championship, but we promoted both seasons

).
Enter new Arse man who thinks better of squad but sayd oldguycentreback is no longer of any use and should be asked to leave the club. He goes on to be 2nd in appearances, and again lead the team in avg rating in the
Prem (where we finished 11th, so there were a lot of guys playing well).
I guess it's genetic to Assmen.
