Midfielder 'Leo' made his first Premiership start of the season in place of Gus Poyet while big defender Anthony came in for Ledley King. Glenn confirmed both Ledley and Gus were rested.
Glenn said: "Anthony and Leo put in great performances for us. Steffen Iversen at half-time - you want lads to come off the bench and affect the game and he did that.
"That's an encouraging sign, that we can bring people in that haven't played recently and they can come in and perform like that."
Glenn insisted that he had wanted to rest Ledley for a while now - before Saturday, the 21-year-old had played in every game this season - and he hinted at Coventry that Gus needed a break.
He explained: "Ledley and Gus have had a lot of football and I wanted to rest them about a month ago but it couldn't be done.
"Ledley's played 31 games this season including England Under-21s and mentally we've seen a couple of things that indicate he needs a rest, Gus the same. He was fatigued after Coventry and it was right to rest him with games coming thick and fast."
Glenn Hoddle took encouragement from the performances of Anthony Gardner, Oyvind Leonhardsen and Steffen Iversen against Everton.
