Not far off Utd's win percentage then
Brighton finished 9th with a lower win percentage and Leicester 8th with roughly a 35% win percentage btw.
I know you're only saying this because it's Gerrard but anyway, what do you expect from him at a club like Villa? The gap between 14th and 8th is less than half the size of that between 2nd and 3rd in the PL. Heck, the gap between Villa and Utd in 6th is smaller than the gab between Liverpool and Chelsea. "Midtable" in the PL is no longer 9th to 11th - there's only the odd win here or there difference between a side finishing 8th or finishing 14th and even if you look lower down, next season the likes of Everton and Leeds could easily end up finishing in the top 10. All PL sides have money these days and are able, with a bit of competence, to put together a half decent squad.
Wasn't the only problem, I'll give you that. But he absolutely was a problem. He spent £140m on two defenders that shouldn't be near a top of the table side and constructed a mish mash of a sqaud full of players that have little or no work ethic.
