A tip for any full-back who comes up against Raheem Sterling this season: if you want to scare the Manchester City winger, simply sneeze loudly.
This might sound weird but if you watch the embedded video further down this page, it’ll all make perfect sense.
Sterling and his England teammates were out on Slovakia’s Štadión Antona Malatinského pitch, ahead of Sunday afternoon’s World Cup qualifier, when Henderson suddenly sneezed behind his former Liverpool teammate.

This gave poor Sterling the fright of his life.
You’ve never seen someone jump so much because of a sneeze. (Scroll down to watch the video).
Video: Henderson makes Sterling jump
Don’t worry though, Raheem, you’re not the only man in football filmed jumping out of his skin following a loud noise.
This fantastic clip of Gary and Phil Neville, back from when they were still Manchester United players, shows them jumping at thunder and lightning.
While we all remember this amazing video of Sir Alex Ferguson almost having a heart attack after Mike Phelan popped a balloon next to him at Stamford Bridge.
Sterling has been excellent so far this season
Back to the football and Sterling will be hoping to continue his excellent early-season form onto the international stage.
The 21-year-old has rediscovered his form and confidence under Pep Guardiola and has been named in Sam Allardyce’s starting line-up, alongside Henderson, for Sunday’s clash against Slovakia.
Sterling was heavily criticised for his performances at Euro 2016 but now looks back to his brilliant best following Guardiola’s arrival at the Etihad Stadium.
"'Reborn', I keep seeing that word,” Sterling told Sky Sports after his Man of the Match display against West Ham last weekend. “It was difficult coming in that first season, and the manager has come in this season and given us a lot of courage.
"I'm not saying that Manuel [Pellegrini] didn't, but [Guardiola has] come in and given me a lot of authority to go forward. He's even had a go at me in the first half for not dribbling as much as I should do, so credit to him for giving me that boost."
