Gary Neville says there is little point predicting who may succeed Sir Alex Ferguson as manager of Manchester United with the Scot showing no sign of letting up at the helm at Old Trafford.
Ferguson will celebrate 25 years of being in charge at United this year, and will turn 70 in December having won his 12th league title last season.
However Neville, one of five United stalwarts to leave the club in the summer, doesn’t expect Ferguson to be leaving any time soon.
"There's no point in thinking about succession planning because he will stay as long as he wants, Neville said.
"I don't see this manager quitting. He is just the absolute best.
"He has health on his side and he looks the same to me as he did 10 to 15 years ago.
"How can you think about succession when you have a man that shows no sign of giving up, no sign of wanting to quit, no sign of not wanting to be the manager anymore?
"For all Manchester United fans, they hope he stays forever."
Ferguson had previously gone back on plans to retire from management, saving the club’s board from making a decision on his successor.
And the former Red Devils skipper believes such a decision will be close to impossible to make come the time.
"The best managers out there at the moment are Pep Guardiola and Jose Mourinho but they are at other clubs - Real Madrid and Barcelona," said Neville.
"Will they let them go? I don't think so. Are they better than Alex Ferguson for Manchester United? I don't think so."
