Jose Mourinho will last no longer than three years at Manchester United, according to the club's former player Phil Neville.

Louis van Gaal led United to their first trophy in three years after lifting the FA Cup on Saturday 21 May but the Dutchman is expected to be replaced by Mourinho this week. The former Chelsea manager was sacked from his post at Stamford Bridge last December after losing nine of his first 16 games of the 2015-16 season, just six months on from winning the Premier League title with the club.

Mourinho left the Blues after just two-and-a-half seasons, having lasted for three years and three months during his first spell at the club between 2004 and 2007.

The Portuguese is one of the game's most decorated coaches but has failed to manage any of his former clubs in Porto, Inter Milan or Real Madrid for longer than three years. And Neville, who spent 10 years at United before returning as a coach in the 2013-14 season, doesn't believe that will change at Old Trafford.

"I can't see him staying too long at Man United, maybe two or three years, that seems to be his shelf life at a football club," Neville said on BBC Five Live.

"When Jose finishes at a club it tends to be a pattern where he falls out with a few players, he gets disgruntled and the team dips. It happened at Chelsea, it certainly happened at Real Madrid where there were rumours he fell out with players. It is a pattern with Jose, he comes into a club, he gets success but he doesn't stay for too long."

United are expected to part ways with van Gaal this week following the club's failure to qualify for next season's Champions League. Despite being presented with the opportunities to jump above neighbours Manchester City into fourth, the club failed to take them and finished the 2015-16 season fifth.
