Mario Gtze juggles chewing gum during Champions League training session

Before Borussia Dortmund steamrollered Ajax 4-1 on Wednesday night to ensure a place in the final 16 of the Champions League, Mario Gtze pulled off some showboating of the highest order during a training session at the unnecessarily capitalized Amsterdam ArenA.

The midfielder skilfully juggled his chewing gum and - unconcerned by its contact with his boots that have been on the dirty ground flicked it back into his own mouth.

Gtze isn't the first footballer to combine juggling and mastication, as bothMesut zil and Rafael van der Vaart have been spotted playing with their Wrigley's during warm-ups.
