But don't worry, it's all for a VERY good cause!
Niall Horan has been announced as the latest celebrity taking part in Soccer Aid 2016, having agreed to be Assistant Manager to the Rest of the World Team. But that means he'll be going head-to-head with bandmate Louis Tomlinson, who is among the celebrity players for the England team.
"It's an absolute honour to be asked to be involved with such a fantastic charity and this game has become a major event on the calendar for the last 10 years," said Niall.
He'll be serving as Assistant Manager to Rest of the World Manager Claudio Ranieri, who just won the Premier League with Leicester.
"I'm absolutely delighted to be a part of the Rest of World team and Mr Ranieri's management team. We have a great team this year and I'm sure the boys are looking forward to the challenge. It's going to be a great week."
Niall will be helping coach celebrities including Hollywood actor Michael Sheen, chef Gordon Ramsay and former Westlife singer Nicky Byrne.
Meanwhile, over on England's team, bandmate Louis will be joined by singer Olly Murs, ex-TOWIE star Mark Wright, JLS' Marvin Humes and Take Me Out's Paddy McGuinness. The England team will be managed by Jose Mourinho, with Robbie Williams serving as Assistant Manager.
The match takes place Sunday, 5 June at Manchester United's Old Trafford stadium and will be broadcast on ITV. All proceeds go towards UNICEF's work helping children around the world.
