David Alaba is free to decide if he wants to move to the Premier League this summer.
But Hansi Flick remains hopeful that "the heart" of his Bayern Munich defence will sign a new long-term contract at the Allianz Arena.
Alaba, 28, has been outstanding at centre-back since Flick’s arrival at the German champions.
With Alphonso Davies’ emergence at left-back, Flick has moved Alaba into the heart of defence - a role he previously filled under Pep Guardiola and intermittently in recent campaigns - and has handed him greater responsibility to lead the side from the back.
However, Alaba’s contract situation, like that of midfielder Thiago Alcantara, has put his long-term future in question.
Alaba’s deal expires in 2021, with chief executive Karl-Heinz Rummenigge declaring last week that they will look to sell players now rather than see them walk away for nothing in 12 months time.
"We don't want to lose a player on a free transfer next year - I will be very clear about that,” said Bayern’s CEO.
If Alaba is ready to depart, then Manchester City will no doubt be at the front of the queue.
Guardiola worked with Alaba in Munich, and as he looks to chase down Liverpool next term is determined to strengthen in defence; Alaba’s quality, both at centre-back and left-back, and Guardiola's knowledge of his character puts him at the very top of City's wanted list.
Chelsea too hold an interest, with Frank Lampard similarly keen to raise the bar where his defence is concerned, having had problems throughout his debut year as Blues boss at left-back while also chopping and changing his centre-backs throughout too.
Should his availability become more clear, Manchester United would likely become an interested party also.
