French newspaper, L'Equipe, reports that Zidane was already making contacts with Manchester United board as he considers taking over Mourinho.
Not much has been heard from the French World Cup victor since then although there were whispers that he was placed on a shortlist by Manchester United management as a backup should Mourinho decide to depart Old Trafford.
Mourinho's relationship with Shaw has been called into question on a number of occasions in the past, with the Portuguese boss publicly criticising the full-back on numerous occasions.
Mourinho is under huge pressure win the Premier League this season after failing to win a trophy at Old Trafford last campaign.
During pre-season, Mourinho lamented the lack to acquire priority targets which seemingly aroused tension between him and club Chief Executive Ed Woodward.
Having won the UEFA Champions League thrice and the LaLiga title in two and half seasons at the Spanish giants, the 46-year-old has been touted as the ideal candidate to lead a new project at the Red Devils.
Since leaving the club in 2011, Van der Sar has gained acclaim from his work at Ajax, where his professional senior career began and it is this post-playing career success which has left him as a viable option to become Manchester United's first ever Director Of Football. However, should Zidane contact the United hierarchy about becoming their manager, they will need to make a quick decision or risk losing the Frenchman to another Premier League club.
