Two goals from Terry Dixon (pictured) secured a significant first half advantage before the home side reduced the deficit on the hour. Jacques Maghoma made sure of the win on 76 minutes.
Clive feels the margin of victory should have been greater, while going to praise his side for their fitness levels and coping with the heat.
"It was a good performance, but we were a little bit rusty with our finishing," said the Development Coach. "We created opportunities and there is some disappointment with our play in the final third, the area where we need precision and quality.
"We let ourselves down on a number of occasions and, if we had shown that precision, we could have run up a nice score and won the game more comfortably.
"Some of the build-up play, movement and confidence of the team in our approach play was very good, but we need a clinical edge around the box.
"It is all about fitness at this stage though and again they looked stronger and fitter. They worked very well and recovered very well. The conditions over the last couple of days have been very hot and we have made sure they know exactly what they need to do in terms of fluids and rest.
"I'm pleased to say they have taken that on board and I think it is reflected in they way most of them put in a good 90 minutes work."
Clive Allen called for his Spurs XI side to be more clinical after they recorded a 3-1 victory over Boreham Wood on Tuesday evening.
