Mourinho has been strongly linked with a move to Man United in the event of van Gaal’s exit at Old Trafford.
McCarthy, a United fan who won the Champions League with Porto under Mourinho in the 2003/04 season, insisted that the Portuguese can get the club back on track.
“I think we need somebody that will steer the ship with immediate results but also as a long-term successor,” McCarthy said.
“The good old days of Sir Alex Ferguson are long gone. I think we have to try and captivate those moments back and for me the only example I can give for someone who can get United back on that path is Jose.”
Mourinho, sacked by Chelsea earlier this season, has made no secret of his desire to return to a top club in England and United seem to be the only viable option.
Numerous reports have suggested that Mourinho is already working on transfer targets ahead of the summer and it seems as if he has some sort of agreement with the club. United’s season has been awful under van Gaal and Mourinho would undoubtedly bring success back to Old Trafford.
