David Luiz joins hair twin Matteo Guendouzi at Arsenal - and we're hair for it

David Luiz is joining Matteo Guendouzi at Arsenal, meaning there will be two impressive heads of hair on the team. So Newsround's taken a look at some of the other biggest, baddest and best haircuts in football!
When Chelsea's David Luiz played against Arsenal's Matteo Guendouzi in the Europa League Final, some people dubbed it the 'hair derby'. Now, Luiz is joining his tresses double at Arsenal. One fan Adam commented: "£8 million for David Luiz might seem cheap for Arsenal in today's market, but imagine how much more they'll have to spend on unblocking the shower drains with these two"

Bayern Munich star Franck Ribery was on the losing side against Liverpool in the Champions League but he made an impact with a special haircut. He got his shirt number - seven - shaved into his head. The thing with statement haircuts is that if you lose the match, it can be a bit awkward...

Manchester United's French World Cup winner Paul Pogba is almost as famous for his hairstyles as he is for his skills! This work of hair art is from his days at Juventus.

Arsenal's superstar striker Pierre-Emerick Aubameyang loves to express himself with haircuts and styles. Just like Pogba, during his career some people have criticised him for spending too much time focussing on his style instead of his performances, but Arsenal fans seem pretty pleased with both.

Wales and Real Madrid forward Gareth Bale isn't the first and probably won't be the last footballer to favour a top knot.

Former England captain David Beckham was another player who appeared to be quite a fan of the top knot look many years ago. He loved it so much that he even had two at once!

Former Manchester United midfielder Marouane Fellaini was another one famous for his big hair. Fans used to joke about whether or not it helped him to score all those headers! Much to many people's disappointment, before he left the club, he cut it short. This picture is from before the Euro 2016 competition when it was dyed blonde.

Unsurprisingly, Fellaini isn't the only player to style his hair with an eye-catching blond hue. His Belgium team-mate and Inter Milan midfielder Radja Nainggolan (who is currently on loan to Italian club Cagliari) is also famous for his striking blond Mohawk.

Talking of Mohawks, Arturo Vidal of FC Barcelona and Chile has always rocked extreme haircuts - who knows how long it took to shave all those stars and stripes into his head!

Whist we're going back in time, the 1980s Colombia midfielder Carlos Valderrama was one of the most recognisable football players in the world of football - and it's not hard to see why from this photo.

Back in 1998, Taribo West from Nigeria took to the pitch with some very, very green braids, which certainly got the spectators talking.
