Pato is yet to make his first appearance for Chelsea, but it looks like he's found a way to fill his time - with novelty facial hair.
The former AC Milan ace joined Chelsea in the January transfer window on a loan deal until the end of the season from Corinthians, in order to help the Blues climb the Premier League table. While he's not yet done that, he's certainly provided a few laughs off the pitch.
Why's that? Well today, his new team-mate Willian revealed he's now sporting what can only be described as a rather fetching moustache.

Willian posted a picture of the pair at Chelsea's Cobham training ground this afternoon, and you can check it out below (it's not a slow news day, honest).
Chelsea boss Guus Hiddink recently confirmed that Pato is currently being put through a rigorous fitness program to get him up to speed before his full debut for his new club.
The 26-year-old's stock has fallen from his days with AC Milan where he was tipped to become one of the best players in the world, but Brazilian legend Zico, who spent time at Chelsea's training ground with the forward this week, believes his loan spell is a 'golden' opportunity to get back to the very top.
'It's a fantastic opportunity for him," the 62-year-old said. "You could even call it a golden opportunity. He's a player who has had ups and downs but he is a top-quality player and I think he will settle at Chelsea and do very well, which will also be very good for the national team.
"When Pato broke through, he was considered the jewel of Brazilian football. He moved to Milan and was doing very well but then injuries came along and unfortunately he really suffered with them. Now he has another chance to prove his quality at Chelsea and get back to his best."
Chelsea's sole focus for the remainder of the season will be Champions League glory, with qualification for Europe's elite competition via the Premier League seemingly out of reach.
The west London club are 13 points adrift of Manchester City in fourth place despite their recent good form under Hiddink since he took over from Jose Mourinho in December.
Chelsea are also through to the 6th round of the FA Cup after their 5-1 thumping of Manchester City last weekend.
