Antoine Griezmann began the formalities of fitness and medical tests on his first day of pre-season as a Barcelona player on Sunday.

The World Cup winner visited his new club's training ground for routine examinations a day after arriving in Catalonia.

Griezmann, 28, joined Barca on a five-year deal after the LaLiga champion triggered his €120million release clause at Atletico Madrid.

His next official duty will be to meet the media for a photo session and news conference before training begins on Monday.

Ernesto Valverde is expected to run the rule over more than a dozen first-team players, including €75m acquisition Frenkie de Jong, with one eye on the upcoming trip to Japan.

Barca faces Chelsea and local club Vissel Kobe, now home to Andreas Iniesta, on July 23 and 27 respectively.

Lionel Messi, Luis Suarez, Philippe Coutinho and the Blaugrana's other Copa America representatives will not be present for the start of pre-season training, having been afforded additional time to recuperate.

Coutinho's future remains uncertain amid claims from his agent that Barca is attempting to offload the Brazil international to Paris Saint-Germain in exchange for Neymar.

Valverde's men finished 11 points clear atop LaLiga last term but failed in its quest for a Champions League triumph, losing out to the eventual winner Liverpool in the semifinals.
