Pochettino was snapped having lunch with the former Manchester United boss yesterday, sparking rumours that he was edging closer to a move to Old Trafford.
Pochettino has been tipped as a potential replacement for Louis van Gaal at United, with the Red Devils looking set to change manager in the summer.
However, the Mirror claims that the meeting was purely because both Pochettino and Sir Alex have a mutual respect for each other.
The pair have previously spoken positively about each other in public, and they reportedly simply wanted to meet up for a harmless chat yesterday.
Indeed, Spurs are believed to remain confident that Pochettino will sign a new deal at White Hart Lane.
Pochettino confirmed that he has verbally agreed a new deal with Spurs which will keep him at North London club until 2021, but he is yet to officially commit his future, with no contract signed.
