Kieran Trippier is key to Cholo Simeone's plans, but the player's future is not certain as Man Utd are determined to get hold of the English international.
The footballer himself, despite being very happy at Atletico, seems excited at the possibility of moving to Old Trafford. However, Atletico keep on counting on him.
According to 'AS', the current league leaders are clear that Trippier is not for sale and they will only let him leave if the player specifically asks to go.
The Red Devils will also have to put in an astronomical offer for the player. They are also negotiating the signing of Real Madrid's Raphael Varane.
At the moment, according to recent information, Man Utd have put 24 million euros on the table for the player, who is now looking for a house in Manchester.
At the age of 30, the Englishman is fundamental for Simeone and the club will try and make him see that he is an indispensable player to persuade him to stay in the Spanish capital.
