Frank McAvennie is shocked Tottenham have handed the manager reins to untried Ryan Mason for the League Cup final against Manchester City. 

The former Celtic and West Ham forward, speaking exclusively to Football Insider, admitted that he’d barely heard of Mason when he took over at Spurs following the sacking of Jose Mourinho.

Mourinho was relieved of his duties on Monday morning after 17 months in charge following last Friday’s 2-2 draw with Everton.

Mason was initially announced as only taking the team’s training session on Monday afternoon but he has since been confirmed as interim boss until the end of the season.

That is a shock move given he is 29 and has not managed at any level before other than in youth-team football.

He faces Manchester City on Sunday as Spurs have the chance to win a first trophy since 2008 and McAvennie claims Mason has a great chance to get his managerial career up and running.

“Brilliant, who is he? No disrespect to him but really, who is he?” McAvennie told Football Insider correspondent Ben Wild.

“Good luck to him, his second game in charge is against Pep [Guardiola], that’ll be good, all the best son. 

“I suppose it’s not that bad because in his situation you’d want to challenge yourself against the best. 

“If you had to come in and have a chance as a promising coach, what a way to prove you’re a good coach while the club look at bringing someone else in, who knows if he’ll be there after the summer?

“Winning a cup and getting one over on Guardiola, that would be fantastic but let’s not get carried away.”

Mason, 29, became the youngest Premier League manager in history as he took charge of his first Spurs game on Wednesday night.

His career got off to a winning start against Southampton as a Gareth Bale effort and a late Heung-Min Son penalty cancelled out Danny Ings’ opener.
