Arsenal midfielder Santi Cazorla could be set for a move away from the Emirates, ITV Sport understands.
The Spanish playmaker, who has struggled to settle into the English lifestyle, is interesting La Liga champions Atletico Madrid, who are looking to form a squad capable of competing in the Champions League.
Atletico have lost Diego Costa and Filipe Luis to Chelsea this summer, so have money to spend, recently acquiring French international Antoine Griezmann.
Cazorla spoke glowing about the Spanish champions recently, saying: Atletico and Arsenal have to play the same way, but everyone is looking to win titles.
"They had an incredible season last year. Winning titles takes several campaigns, I admire everything they have conquered. Many people do not realise how hard it is to win a league competing with Barcelona or Madrid."
If Arsene Wenger does offload the the former Malaga man, it would free up money to make a move for German international Marco Reus, who recently rejected a new deal with Borussia Dortmund.
Reus would be an upgrade on the 29-year-old Spaniard, after impressing at Dortmund over the past two years, and would be interested in trying his luck in the Premier League.
