Pundits were quick to point out that boss Glenn had now signed a 33-year-old alongside 35-year-old Teddy Sheringham when the Uruguayan international was unveiled on Sunday.
But Glenn declared: “I’m not worried about his age. Some people will look at Teddy’s age and Gus’s age but I’ve looked at their records, looked at how many games they’ve played, how fit they are and what desire they’ve got.
“You have to have a desire to play until you are 37, 38 and I think these guys can do that.
“The main thing for me is that he is a class player, he knows the English game and he knows how to win things, like Teddy, and those are the players I’m going out to get because it’s an ingredient the club hasn’t had for a long time.
“To bring youngsters in with the youngsters we’ve got I feel would be a mistake.”
Glenn was naturally delighted that the midfielder chose Spurs ahead of Liverpool - who Gus confirmed were interested in the press conference - and a host of top European clubs.
He said: “It’s a significant thing for the club and the fans should know that, I’m not naming names, but top, top teams in this country and in Italy and Spain were interested and he’s chosen Tottenham.
“He’s chosen to come here. He’s seen the ambition of the board, he’s seen the ambition of myself and the staff.
“He’s a person who likes to enjoy his football and his training. I think he will enjoy himself here. I’m delighted to have him.
“Gus is an infectious character and that’s very important. I hadn’t met him but you could see that through the television.
“People who worked with him at Chelsea said he had a great personality that lit up the dressing room. As soon as I spoke to him you get that from him.
“He also takes that out on the pitch with him and turns that bubbly character into a passion on the pitch. Players will learn from him.”
Glenn Hoddle has insisted age is not a barrier after Gustavo Poyet joined his new era at the Lane.
