Manchester United and Chelsea would be "mad" not to consider Tottenham boss Mauricio Pochettino as their next manager, former Spurs captain Jamie Redknapp has said.
Louis van Gaal is under growing pressure at Old Trafford, with sources telling ESPN FC that ex-Chelsea manager Jose Mourinho has been contacted about the United post.
The Blues, meanwhile, are looking for a permanent successor to Mourinho, with current coach Guus Hiddink only having been appointed until the end of the season.
Following their 2-1 victory at Manchester City on Sunday, Pochettino's Tottenham are two points off the top of the Premier League and the 43-year-old's stock is continuing to rise.
Redknapp, whose father Harry was the last manager to lead Spurs to a top four finish, wrote in the Daily Mail: "If I were [Spurs chairman] Daniel Levy, I would be knocking on Mauricio Pochettino's door with a huge new contract.
"Tottenham have had six managers in the last 10 years. Now they have one they simply have to keep.
"This summer it looks like Chelsea and Manchester United will be looking for new managers. They would be mad not to look at Pochettino.
"He ticks every box an owner requires. He plays good football, gives kids a chance and gets his teams so fit and organised.
"And, importantly, it's not all about him. He proves you can still be a top boss without being arrogant."
