Carlos Vela will return to Arsenal next season, the president of the forward's current club, Real Sociedad, said on Tuesday.
The Gunners can activate a clause in the former Mexican international's contract to bring him back to the Emirates, and Sociedad president Jokin Aperribay confirmed the move, telling Spanish radio station Cadena SER: "Arsenal have informed us that Vela would be with them next season."
Vela, 25, previously played for Arsenal from 2008-2010. He initially joined Sociedad on loan before securing a permanent deal two years ago.
He excelled this season, scoring 16 goals in 34 games, prompting Arsenal to call him back for a reported 3.5 million pounds.
Vela was not selected to join Mexico's World Cup squad after repeatedly declining call-ups during qualifying.
On Vela's future, his Mexico teammate Andres Guardado believes he would be a good replacement for reported Chelsea target Diego Costa at Atletico Madrid
Guardado said: "It is difficult to replace Diego Costa, and also to arrive after Atletico have won La Liga. Unfortunately such a situation can be counter-productive for a new player arriving.
"But Simeone is a coach who does not let anyone relax. This would be very good for Vela, and I believe he could play at a very good level at Atletico."
