I think you'll find he left because he was a gutless wimp who had wasted Millions and been told enough was enough .
Had we spent £120m on some quality and showed some real ambition and not seen 6th as some sort of new 1st the likes of Mellberg Barry and Milner would have stayed.
to say team spirit was good under MON is a joke , ask luke Young, Curtis , Sidwell, Coker, Shorey Harewood Guzan not to mention Sorryson and previous players the vindictive little man had frozen out without explaining to them why .Not a single players has said they are sad to see him go !
He's gone get over it and move on
