Former Manchester United chief executive Peter Kenyon has claimed that Jose Mourinho's appointment at Old Trafford could be the club's "biggest ever signing".
The Portuguese was officially announced as the Red Devils' new manager on Friday following five months out of the game since his sacking at Chelsea.
It was at Chelsea 12 years ago that Kenyon, then working behind the scenes in West London, brought the self-proclaimed 'Special One' to English football for the first time.
Kenyon is now expecting Mourinho to bring success back to United in the same way that he did at his former suitors, citing the 53-year-old's "winning mentality" as a key reason behind his impression collection of silverware.
"When I appointed him I was looking for someone who could bring a winning mentality to what was already a good team," he is quoted as saying by Metro. "What Jose brought was a winning mentality and that led to Chelsea winning their first title in 50 years that season.
"That's the ability he has. He makes good players better. Everybody talks about new signings but the current players at Manchester will be better under Jose Mourinho.
"They'll get a coach who brings new techniques, new developments and forward thinking. I think he'll have an immediate impact. It's United's biggest ever signing."
Mourinho has won 22 trophies since 2003 during spells at Porto, Chelsea, Inter Milan and Real Madrid.
