Arsenal manager Arsene Wenger has revealed that Alexis Sanchez is already focused on the Gunners' next campaign, despite only just winning the Copa America with Chile for the first time in the history of the tournament.

The Chilean international scored the winning penalty for his country and the French manager admitted that he was "over the moon" for his player.

Sanchez joined the north London club from Barcelona last summer, and took to the Premier League like a proverbial duck to the water. He scored 25 goals and provided 12 assists in all competitions last season to help Arsenal finish in third place in the league and retain the FA Cup they had won 12 months previously.

Wenger was delighted for Sanchez and believes that the player is as hungry as ever to win titles and revealed that the former Barcelona man is keen to win more trophies with Arsenal following his back-to-back triumphs for club and country.

"I texted him [after the final] and he texted me back. He was already focused on next season with Arsenal and wants to win everything with us. He was thrilled and very happy," Wenger told Arsenal's official site.

"They had quite a comfortable lead when he took the penalty but I was a bit worried because he missed one with us."

"He has shown again that he is scared of nothing. He took the ball and chipped the keeper. It was quite audacious but I was of course over the moon to see him bring the trophy to a country that has waited for such a long time," the French manager explained.

"It is an historic achievement and when you're a football player, you want to do that, so I'm very happy for him," the Gunners boss added.

Arsenal are certain to be without Sanchez for their Community Shield clash against Chelsea, and he could also miss the start of the season as the manager confirmed that he will only return to first team training on 3 August, which is just five days before the Gunners take on West Ham United in the opening day of the Premier League campaign.
