After being aware of Guimaraes' situation, Atletico now know that any club can take the player away at any time.
According to 'Mundo Deportivo', the preferential option that Atletico Madrid had, has expired and this makes things a lot easier for their rivals.
Interestingly, Athletico Paranaense, as their President says, confirmed this Sunday that Benfica have made an offer for the player.
"Yes, it's true. We have got an official offer from Benfica for the signing of Bruno Guimaraes," Mario Celso Petraglia said in 'The Game'.
