Messi already drives his PSG teammates crazy in training!

While Paris Saint-Germain fans are impatiently awaiting Lionel Messi's debut, to see the former Barcelona captain donning the French side's shirt, the Argentine is impressing by demonstrating his skills in PSG's training.

In a video taken during a session, Messi can be seen using his trademark runs and changes of pace during a game on a reduced-size pitch.

The Argentina international had agreed terms to renew his contract with Barcelona earlier this summer, but the Blaugrana's financial issues forced the club to part ways with him. Following his departure, Messi reached an agreement to join PSG, where he will join forces with former Real Madrid captain Sergio Ramos, who also departed to France on a free transfer this summer.
