Manchester United have reportedly identified Zinedine Zidane as a potential replacement for Jose Mourinho.

United are currently preparing for their third campaign under Mourinho, but the Portuguese has recently suggested that he is growing frustrated with the club's efforts in the transfer market.

Mourinho has also failed to last longer than three years in his last three roles, and according to The Sun, United have already started to put contingency plans in place.

The report claims that Zidane would become United's top target should Mourinho leave the Premier League giants, with the Frenchman available after departing Real Madrid earlier this summer.

Zidane is currently taking a break after his trophy-laden spell at the Bernabeu, but is suggested that taking over at United in the future would likely appeal to the 46-year-old.
