Pochettino, sacked by Tottenham a year ago, said he is ready to take on a new challenge – with the 48-year-old firmly in the frame for the Old Trafford job.

Solskjaer finds himself under pressure after taking just seven points from a possible 18 this season, with United languishing down in 15 place in the Premier League.

United have picked up a solitary point at Old Trafford this season, three defeats and a draw making Solskjaer's position increasingly uncertain, with Pochettino ready and willing to step in.

The ex-Hearts captain, who also spent time with Leeds United and Rangers, had been privately battling illness.

His wife announced on Saturday that the defender had passed away, 11 days before his 37th birthday

Nora Zaliuke wrote on social media: "He will rest peacefully in eternal silence.

"The heart of Marius Zaliukas stopped beating today."

The news was announced during Hearts’ Scottish Cup semi-final win over Hibs on Saturday.
