Argentina's open training session ended in disorder on Wednesday as more than a dozen fans invaded the pitch.

Security guards couldn't stop the fans from running up to Lionel Messi and his teammates as they walked off the pitch at Independencia stadium in Belo Horizonte.

One fan knelt down in front of Messi and started shining the Argentina captain's boots. Messi laughed, received a hug from the fan and gave him his sweater before a security guard pulled him away.

Other fans ran off with one of the balls that the Argentines had used during the training session.

Some 10,000 people watched the session, many of them Brazilians wearing the shirt of Brazil's biggest rival.
