Manchester United have enjoyed a fine start to the season, winning seven of their first Premier League games and clocking up three victories from three in the Champions League.
But recent comments made by Mourinho has seen his Old Trafford future plunged into uncertainty, with the 54-year-old confirming he has no desire to see out his managerial career with the club.
He also suggested that he would be open to managing PSG, at a time where Unai Emery's future at the Parc des Princes is also up in the air.
However, Balague thinks Manchester United have no hope of bringing Pochettino in – with the Argentine seemingly happy to be at Tottenham for the long term.
