VIDEO: Luis Suarez jokingly takes swing at teammate Sergi Roberto in training

Is Barcelona forward Luis Suarez up to his old antics?

The Uruguayan striker, famous - or, perhaps, infamous - for sinking his teeth into the opposition, was filmed goofing around in training, pushing around his teammates while laughing, and even taking a swing at poor Sergi Roberto.

Suarez was, of course, just messing around, and Roberto took the "punch" with a laugh as they returned to regular training drills shortly after.

Still, it makes you wonder: will Luis Suarez strike again?
