I honestly think Martinez would of gone on to Villa and achieved very good things, I rate him quite highly. I'm pretty shocked they couldn't attract him because they are a big club and are quite attractive, or at least you would of thought.
McLeish is a decent manager who will make them hard to beat and probably do well in the cup competitions as a result. Hard to predict what he can achieve with them in the league though, it's vital he gets off to a good start to keep the Villa fans sweet. If he can manage that he can push a top 8 finish with the right signings.
Be interesting to see who they do go after in the market, they've got the goalscorer in Darren Bent and have good solid defenders in Dunne and Collins, I also rate Warnock. Brannen and Albrighton are decent youngsters, Ireland as we know is a good player when he's on it. However, they must keep hold of Downing with Young leaving, and need some fresh faces in midfield and a new goalkeeper, quite the task McLeish has took on and deserves some admiration imo.
