Manchester United legend Gary Neville has insisted that the next season will be very critical for both Mourinho and Guardiola.

According to him the competition between manager Jose Mourinho and his rival Pep Guardiola will be tough.

Both managers have bagged 20 titles after Manchester City being crowned the Premier League champions last weekend.

Guardiola’s side have clinched the title following Red Devils’ 1-0 defeat by bottom club West Bromwich Albion on Sunday afternoon.

Former United defender Neville believes the two managers will be on a collision course next season as everybody wants to outshine his counterpart.

“When they both came in Manchester two years ago this was going to be a collision course,” Neville told Monday Night Football.

“There was always going to be a winner and a loser. If you look at the head-to-head of these two managers and the titles they have won, they have won 20 titles each.”

“If Manchester United were to win the league next season, Jose Mourinho would say that he’s come out on top over the three years period. If Pep Guardiola wins the title next season he will say he is starting to dominate English football and produce a great side, saying his team are the winner and he is the winner so next season is critical.”

“This season there is no doubt that Guardiola has stolen in front. Mourinho can still end the season with a trophy to add to the two of last season, so you can’t say he’s been a failure but over a three-year period, it’s who wins the Premier League titles that will come out the winner.”

“Next season is absolutely critical for both managers.”

Guardiola has managed to lift 7 league titles and two Champions League trophies in three different clubs; while Mourinho bagged 8 league titles and two Champions League trophies in five European clubs.
