Saul Niguez is ready to leave Atletico Madrid this summer.
The Spain midfielder is considering his options after losing his first-choice this season under Atletico coach Diego Simeone.
Saul has been a long-term target for Manchester United and AS says his current frustrations have reached clubs across Europe.
Bayern Munich have been quick to act and are in contact with Saul's camp to register their interest.
The midfielder's contract carries a €150m buyout clause, though Atletico are prepared to cash in for €35-50m this summer.
