Manchester United target David De Gea has been told he must sign a new contract with the club or risk being shown the door at the Vicente Calderon, reports talkSPORT.
The Spanish keeper has been strongly linked with a move to England with reports the La Liga side had accepted a bid of £18 million from the 18-time league champions in the last month.
With Athletico keen to tie De Gea down to a longer deal, Madrid's CEO Miguel Angel Gil Marin says the keeper may have to leave the club, with United on red alert.
"We have met with him to negotiate a new deal on two occasions," Marin said on Onda Cero Radio.
"He has a contract with Atletico for three more seasons, so it is necessary to renew it and reasonable to revise his salary, which is well below his current performance.
"But at the end of the season there will be two choices - to renew or to leave."
The news will be welcomed by United who were expecting a rough ride in trying to tempt De Gea to Old Trafford, but Marin's latest comments may open the door for the 20-year-old to move to England.
United are expected to be in the hunt for a new goalkeeper after Edwin Van der Sar revealed his intention to retire at the end of the current season.
