Pochettino has been out of work since leaving Tottenham in November last year and has been linked with some top jobs including United and Bayern Munich.
The right opportunity has not presented itself just yet, for whatever reason, but he says he is rested and raring to go again if the right job becomes available again.
Managing in the Premier League would be his preference, and the best chance of that happening could be with United, as pressure continues to mount on Ole Gunnar Solskjaer.
Ed Woodward has insisted that United will keep faith with Solskjaer as they look to rebuild the Reds squad, but while Pochettino is out of work, the rumours will not go away.
They were fuelled even more on Tuesday night when Pochettino was spotted watching Brentford versus Leeds United, and was in close proximity to Woodward's new PR man Neil Ashton.
