Decent chap, rubbish manager.
Great chap, great manager.
You only need to see how they played last season and where they finished.
This season, well lets see, they were in massive debt, sold maybe their best defender(look at Villa's record with Collins in the team) and have had a worse injury list than any other club.
Off the top of my head, players who missed a significant number of games who played a MASSIVE part the previous season.
Ilunga, Parker, Cole, Collison, Upson, Noble, Faubert, Zines(i think), Boa Morte. The problem being that Ilunga, Parker, Cole, Collison, Upson were the best players in the team last year.
Now they've also had injuries to, Tompkins, Mido, Behrami(who came back from an AWFUL injury and only hit decent form in the past 5 games).
Basically the whole squad at one time or another has missed more than a few games, with most of the key players missing huge portions of the season.
Arsenal without Gallas, Fabregas, RVP, Vermaelen, Clichy, Song, Arshavin for a pretty large portion of the season is what West Ham had, and more. We've had those players injured and its taken a huge toll, but other than RVP, Fab and CLichy the others played the majority of the season.
Without those injuries they'd have easily had another 20 points, and probably be pushing Everton/Liverpool hard for European places.
West Ham have had a far worse time with injuries than any team and they still survived, maybe only just, but they did. Ridiculous to sack him because more than half the team missed significant portions of the season.
EDIT:- The added problem being, Parker/Faubert/Cole/Collinson played quite a lot of minutes, but it was clear as day that so many games they did play they were carrying injuries, no where near full fitness and extending the amount of time they were injured for.
He had them playing great football last season and in parts this season with a truly crippled team West Ham still looked closer to a proper football team than many others. The problem is who they'll be able to get in to take a crippled team and crippled finances forward, won't produce the good football Zola proved he was capable of when not crippled by injuries. Zola could have done fantastically well for them in a fresh season with most of the injuries behind them, someone else, is likely to suck and go into panick mode buying up crappy "scrappers" and brawl their way into the Championship.
