Gus Poyet has done a magnificent job at Sunderland, taking over from Paolo Di Canio in October and saving the Black Cats from what appeared to be certain relegation.
One of his strengths has been his decisive substitutions, and Emanuele Giaccherini has been particularly impressive.
The Italian has come off the bench seven times, scoring twice and providing three assists in that time.
