Celebrations are becoming more and more important in football. So much so that EA Sports have now incorporated them into their FIFA games.Gone are the days that Alan Shearer’s ‘hand-in-the-air’ style will suffice.Instead, footballers are now coming up with bizarre ways to celebrate after finding the back of the net.Last season, we saw plenty of players performing choreographed handshakes with teammates.While football fans may cringe that these rehearsed handshakes, at least they don’t get into trouble with referees for their celebrations.Players are more than aware that jumping into the crowd or removing their shirt means they will pick up a yellow card.One man that doesn’t seem to care, though, is Roberto Firmino.The Brazilian has picked up seven bookings in the previous five seasons for ripping off his shirt after scoring - more than any other player in Europe’s top five leagues.He really needs to come up with something new.And maybe he has.That’s because he was seen producing a very strange celebration after scoring for Liverpool during their Champions League qualifier against Hoffenheim.The striker pulled down his shorts a bit and did a little jiggle.

Well, one Liverpool fan has finally got to the bottom of it.

It may have taken him 24 hours but he came to the conclusion that the inspiration behind it was actually Brazilian legend Ronaldinho.

Four years ago, Ronaldinho scored a penalty for Clube Atletico Mineiro and alongside with a few teammates, performed the odd celebration.
