Manchester United legend Ryan Giggs has stressed that the Red Devils could see their next Premier League title after 20 years as told via Sky Sports.
United have not seen the Premier League title since Sir Alex Ferguson called time on his managerial career at the end of the 2012/13 season and David Moyes, Louis van Gaal and Jose Mourinho have since been fired during that time.
"It could be 15, 20 years before you know it, especially if (Jurgen) Klopp and (Pep) Guardiola stick around," Giggs told Jamie Carragher, on The Greatest Game podcast.
"They have got the resources and the players so we have Liverpool to look at where the last time when they won it in 1990 they thought we'll win it again soon.
"Even Klopp took four-and-a-half years for him to win it - it takes a long time. You have to think about what Klopp did.
"He improved the team every season or won a trophy like the Champions League and then you saw the improvement so the pressure was off a little bit.
"Every manager and signing is seen as that he will win us the league and it's not like that."
"The best feeling I always had was leaving Anfield after winning even if Liverpool weren't the best side at the time," said Giggs, who won the Premier League title a record 13 times while at United.
"I played for Salford boys and our toughest games were always against Bootle, Liverpool, Kirkby, Sefton.
"As soon as you went down the East Lancs it was a mindset it's going to be a tough game and a test of not just your footballing ability but also your mental strength."
