I don't think City will stay the course. Our two rivals for 4th are Villa and Liverpool.
Villa have a chance because they're not in any cups so can focus purely on the league. They're also in decent form right now. Working against them however, they have a reasonably small squad so could suffer from injuries as the season comes to an end. They also don't have many players that have competed at the business end of a season so could suffer from a lack of experience.
Liverpool have plenty of players so shouldn't be tired, especially as Beneathus' rotation early in the season was designed to keep players fresh for now. However they're in awful form and are still competing in two cup competitions. The CL in particular could distract them and at this stage of the season it's always better to have the points won rather than games in hand. With the financial implications of them not qualifying for next years CL the pressure will be really on both the players and manager. Can they handle it?
And then of course there is us. We're not playing well right now but are still grinding out results through great defence. In our advantage is the fact that we have no long-term injuries, and the likes of Pienaar, Yakubu, Graveson, Baines and Gardner will all be returning to the side in the next few weeks so we shouldn't suffer from a lack of players having pretty much 20 senior outfield players to choose from. I also think we've had some shitty decisions over the season thus far. If things do even themselves out as is suggested then we're due some luck in the coming months. We might even win a penalty before the season's out. The UEFA Cup could prove a distraction but we've coped with it pretty well so far.
Should be interesting.
