Is the Tottenham Hotspur boss heading back to Spain?
Pochettino, 44, is one of the finest young managers in European football and the Argentine has done a superb job since joining Spurs back in 2014.
The North Londoners mounted their first real Premier League title challenge last season but a third-placed finish still saw them secure Champions League football.
He has had a huge impact on Tottenham in a relatively short space of time; so much so that chairman Daniel Levy tied him down to a deal which runs until 2021.
But The Mirror have claimed that Atletico could come calling at the end of the season to bring the former Espanyol boss back to the Primera Division.
It goes on to report that Real Madrid would also be interested and Tottenham fans might well be sick of hearing about their key personnel being linked with a switch to the Bernabeu.
Luka Modric and Gareth Bale both joined the Spanish giants within the past four years and Levy, the report says, will be desperate to buck that trend and keep Pochettino in North London.
His future could hinge on what Tottenham do this season. They were knocked out of the Champions League at the group stages, finishing third behind Monaco and Bayer Leverkusen, while they are also 10 points behind top-of-the-table Chelsea.
They have not quite kicked on from the promise they showed last season and, at the moment, it looks like the best they can hope for is another top-four finish.
