Guus Hiddink insisted he doesn't deserve the credit for Diego Costa's return to goalscoring form for Chelsea after the Spain international bagged a brace for the Blues to earn a point in a 2-2 draw against Watford at Stamford Bridge on Boxing Day.
Jose Mourinho's successor actually downplayed his role in Costa's revival after his first game officially back in charge at Chelsea, according to ESPN's Liam Twomey:
Hiddink asked what he's done with Costa: "Nothing. Don't over-estimate the influence of managers!" #cfc

It was certainly a rare prolific day for Costa, as WhoScored.
