Tottenham boss Harry Redknapp expects Alan Shearer to get bitten by the managerial "bug" and stay at Newcastle beyond this season, even if they are relegated.
Shearer has been appointed until the end of the campaign to keep the club in the Barclays Premier League, but Redknapp knows coaching can be addictive.
"I think he is probably getting the bug for it and probably enjoying walking into training every day. The buzz he will get from winning, he will think 'I need this'," said Redknapp.
The Spurs boss added: "I think once you are into it you are bitten by it - the ups and downs. We've all had ups and downs no matter who you are, even Sir Alex Ferguson."
Shearer's men travel to White Hart Lane on Sunday and their task is to inflict a second home defeat for Spurs since Redknapp's arrival nearly six months ago.
Redknapp feels Shearer will save Newcastle's season as they have three home games left in the campaign.
Even if they do get relegated, Redknapp believes Shearer's reputation will not suffer, and he wants him to do well and establish himself as a bright, young coaching talent.
"He has gone in there and with eight games to go he can't lose as it is not his fault as he never put them in his position," Redknapp said. "If he gets them out he is a hero.
"We need a Shearer, a young English guy to come through so that when we are looking for an England manager we can go, 'One of those guys has done well. Give them this'. That is what I'd love to see."
