During a recent photoshoot for an endorsement, f(x)'s Sulli showed off her surprising football tricks and skills. It's not clear as to what the endorsement is for, but what's certain is that Sulli is quite talented at football. She must have played back in the day, because she can do tricks that most girl group members definitely cannot pull off. In this short, behind-the-scenes footage clip, you can check out Sulli kicking the ball around, kicking it in the air, heading it a few times and then shooting it right into a little "goal". Check it out below!
