Ole Gunnar Solskjaer has made a fantastic start to life in the dug-out at Old Trafford. But it appears that United are still determined to make a marquee appointment in the summer when his caretaker spell ends.
The Telegraph reports that Pochettino remains their first choice, but the Red Devils are becoming increasingly worried that the Argentinian will decide to stay with Tottenham rather than become the latest to try and get the club back on track.
It would be a major statement from Spurs if they managed to convince Pochettino to stay. There will be plenty who will be expecting him to leave amid the frustration over the new stadium and lack of movement in the transfer market.
But on the other hand, the likes of David Moyes, Louis van Gaal and Jose Mourinho have all shown that enjoying enough success with Manchester United is no guarantee.
Of course, United have the potential to do significantly better than they are currently doing. But Spurs have a lot of potential as well, so it should perhaps be no surprise if Pochettino decides, come the summer, that staying put is the best decision for him.
