Paul Ince has called for Manchester United to back under-fire manager Jose Mourinho but believes ‘football has changed’ since the Special One was in charge at Inter.

Mourinho remains to this date the only manager ever to have won the treble with an Italian club, but since leaving San Siro in 2010 he has endured three tough spells in charge of Real Madrid, Chelsea and United.

Ince, who left the Red Devils to join Inter in 1995, where he spent two seasons, does not want to see him sacked but worries that the game has left Mourinho behind in recent years.

“I hope (Mourinho stays) because Manchester United had Sir Alex Ferguson for so long and I don’t want us to become a yo-yo club with managers sacked every two years,” he told the Daily Mail on Sunday.

“What Mourinho has to understand is the game has evolved. It’s not like when he was at Inter in the Champions League and he could park the bus defensively.

“The philosophy he’s had at Chelsea and Real Madrid has been different to what it should be at Manchester United.”
