Manchester City striker Sergio Aguero was called to the court at the ATP World Tour Finals in London to have a brief knock-up with Juan Martin del Potro yesterday.
The Argentina tennis pro, who is a friend of the Man City forward, hit a few balls with the 24-year-old, who fired one shot far into the crowd with his racquet.
Minutes later the pair left the racquets behind and showed off their keepy uppy skills with the tennis ball to the delight of the crowd, who earlier watched Del Potro defeat Janko Tipsarevic 6-0 6-4.
Meanwhile, Chelsea playmaker Juan Mata was also in attendance at the O2 Arena yesterday.
