Borussia Dortmund, Valencia and Atletico Madrid will reportedly battle for the services of Barcelona winger Cristian Tello this summer.
The 22-year-old has a contract at the Camp Nou until 2018, but it is understood that he will be allowed to leave this summer in search of first-team football.
According to Mundo Deportivo, Dortmund have emerged as the favourites, but Valencia and Atletico are also both keen on keeping the Spaniard in La Liga.
Tello's current release clause reportedly stands in the region of £20m.
