Burch, recently returned from a loan spell at Conference side Woking, produced several stunning stops during the game, but his all round performance also caught the eye of the Scot.
"Burchie was very good, he hasn't had too many reserve games, but ones he has had he's been very good," he said.
"Here you could see the advantage of him going to Woking and playing in the games against men. He dealt with set plays and crosses and played like a mature player.
"Apart from that, he made a number of very good reaction saves, his kicking was very good and he was a good presence."
After the hectic opening exchanges, Spurs settled into a rhythm and reaped their reward with a superbly crafted goal created by Ben Bowditch and executed by Yeates.
In the second period they were forced to scrap to protect the advantage and did so with honours.
"It was a bit of both really, added Colin. "In the first half we eventually got into a style of play but, whatever game you play, normally you've got to win the battle and we dug in and were fairly dogged.
"Eventually we got into how we wanted to play and found the little gaps. We ended up scoring a good goal I thought, a very good goal.
"We were a young side in the second half and they seem to be taking on board and revelling in the chance of playing reserve team football. They've got enthusiasm and here they showed they've got endeavour and a bit of grit.
"They stood up to the battle and the spirit and determination they showed was a real good sign for the future."
Reserve boss Colin Calderwood was full of praise for young keeper Robert Burch after his heroics saw to it that the goal from Mark Yeates was enough to overcome Watford at Vicarage Road on Thursday evening.
