Not surprised he's been offered a new contract despite them not having a permanent manager. Man Utd have said publicly that they're moving away from the manager having autonomy over the squad and clearly as a club they rate him.
Haven't been on their forums but I live in Manchester and speak to several season ticket holders who all speak highly of him as he does offer something different to their flashier players. I think if, as reports suggest, Fellaini & Herrera move on after this season then he'll start to gradually get more game time.
