Former Manchester United defender Phil Neville says new manager Jose Mourinho is the best the club could have opted for.
The Portuguese is expected to be named new club manager at the start of next week and will take over from Dutchman Louis van Gaal.
He was fired by Chelsea in December after a set of disappointing results at Stamford Bridge but will fight straight away for the title next season according to the 39-year-old.
"For as long as I've known it you've got to be the best at Manchester United," Neville told BBC Sport.
"Mourinho is a proven winner. United fans want a team challenging for the league title, they don't want a team finishing in seventh or fifth.
"When Jose finishes at a club there is a pattern where he falls out with players, gets disgruntled and the team dips.
"I can't see him staying for too long at United - maybe two or three years seems to be his shelf life at a club - but as long as he brings success United fans won't be unhappy.
"The pressure of football management and demands from owners and supporters and media now means two to three years in a job is enough.
"He is not the type of manager that will come in and say this is a transitional period and finishing fourth in the league will be enough - that won't be enough for the United fans.
"I am a Manchester United fan and next season I want them to be winning the league. That will be the demands put on him and I am sure he will have the same expectation."
