The Mirror says Zidane has told friends he expects a call from Old Trafford chiefs if the crisis engulfing Jose Mourinho spirals out of control.
Despite Old Trafford executive vice-chairman Ed Woodward insisting that the club are still backing under-fire Mourinho, Zidane has been placed on standby if there is a change of heart.
It's why he has been compiling a short-list of players he would like to bring to Old Trafford to help him turn around the club's fortunes.
It's claimed players on Zidane's list include Real Madrid's Toni Kroos, Bayern Munich's Thiago Alcantara, James Rodriguez – currently on loan at Bayern from Real Madrid – and Paris Saint-Germain striker Edinson Cavani.
Zidane has a burning ambition to manage in the Premier League and a club like United would complete the dream.
