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.

The rumour comes from a reliable source and this isn't the first time that Zidane has been linked with Manchester United.
