Having read dozens of views on Maresca here's mine.
1. He knew what the situation was when he joined, he was just there to Manage.
2. He was OK with that and initially did well with what he had, no problem, won 2 Trophies.
3. As time went on however, a couple of things changed.for the worse for him.
(a) The instructions from above widened to include medical advice, pressure on who to play and who to sub and when.
(b) The Owners refused to give him players needed to replace injuries especially Levi Colwill. Maresca was rightly really pissed off.
4. As for team performances, Maresca for his part either cannot change his boring style, OR he decided to do exactly as told and let us flounder. Either way, he did not improve the performances nor adapt the Team well as a good Manager should.
5. And so he's either not a good Manager for Chelsea, or he decided a way out without risking his pay out.
6. He forced the Board to act, so good on him from my standpoint ,he got what he wanted and from a weak position.
The Owners and especially the dopes Winstanley and Stewart are now the "bad" guys and have been completely exposed as incompetents.
It is them who will now cop all the grief and vitriol they deserve, as no one now doubts their stupidity or greed.
