The Special One shocked fans and rivals on Friday by shaving his head, but there's quite a funny story behind his change of style.

Jose Mourinho caused quite a stir last week, when he decided to shave off the head on his hair. While some fans and experts believed that this change of look had something to do with the so called "war haircut" he had referred to back in his days coaching Chelsea, the reason behind it was quite hilarious.

In an interview with Sky Sports, Mourinho discussed a variety of topics about his return to the Premier League, and inevitably, the talk circled back to why he had chosen to shave his head. When asked about the issue, Mourinho couldn't help but laugh about the reason: he fell asleep while having his hair done.

Tottenham will return to action on Sunday when they host Aston Villa, as they continue their pursuit of a top-four finish. As of now, Mourinho's men are two points behind Sheffield United and four away from Chelsea, who are holding on to the fourth spot in the Premier League.
