Peter Schmeichel has a stark warning for those Manchester United fans hoping to bag Pep Guardiola if and when he decides to leave Bayern Munich.
Louis van Gaal has done a decent job at Old Trafford since arriving in 2014, but his future beyond the 2016/17 season is still in some doubt.
Ryan Giggs has been tipped to take the reigns, but the powers that be would almost definitely jump at the chance to bring the former Barcelona manager to the club.

But Schmeichel, who played 292 games for Manchester United across eight seasons, sees Guardiola as his worst fear as far as his former club's identity is concerned.
"This is my biggest fear that someone like Pep Guardiola will become the next Manchester United manager," he told Sky Sports.
"Guardiola has a way of playing, he has a system and he sticks to that. He has changed Bayern Munich from what I thought was a fantastic treble-winning team under Jupp Heynckes.
"[They played] quick football, through the middle, using the width of the pitch, but they were passing the ball and killing everyone they played against. He started to make them pass the ball sideways and I don't think they are as exciting as what they were."
But Schmeichel's worst fears may have already come true. The Manchester United team on display in the last four games have been a far cry from the exciting sides that won countless titles under Sir Alex Ferguson.
The Old Trafford crowd sang "attack" towards their team during Tuesday's game against CSKA Moscow and booed loudly when Anthony Martial was replaced by Marouane Fellaini.
Until Wayne Rooney scored his close-range header, Manchester United had failed to score in over six hours of football. That run included a 120-minute stalemate against Championship outfit Middlesbrough and what many pundits considered to be a lucky 0-0 against Crystal Palace.
Rooney may have earned them a 1-0 victory with 11 minutes remaining, but almost every fan it that stadium would have swapped Guardiola's "sideways passing" for whatever they were doing last night.
