This is second against fourth in the Premier League, a clash between two sides who have carved up the last seven titles between them, but somehow it does not feel like it. United have won eight of their last 10 fixtures in the league but are grinding out results in their pursuit of Manchester City. Chelsea, meanwhile, stumble and stutter in their attempt to hold on to the final Champions League spot. Neutrals must hope that at least one of these big beasts can rediscover their mojo come Sunday tea-time.
