With a young group - only Radek Cerny, Philip Ifil and Reto Ziegler - providing any Premiership experience, the boys held their own without really threatening in the opening stages before really getting to grip with the game and eventually winning it through Kieran McKenna's second half header.
It means the team remain unbeaten in their four outings so far this season, with a record of three wins and one draw.
"The first goal was always going to be the vital one and we worked hard to get that," reacted Clive. "It was a sluggish start and, with having not played last week, it took us a little while to get going.
Again we showed good resilience against a strong Reading side, it was a big test for the young lads and I thought they came through it well.
"It was always going to be difficult but we came away from home, kept a clean sheet and limited them to very few chances. We handled it all well and it was another good learning curve for the lads.
"As the game wore on I thought the way we broke play up and counter attacked was very good."
The downside of the evening was the injuries suffered by Charlie Lee and Jacques Maghoma.
"Charlie twisted his knee and Jacques strained a hamstring and obviously we will review both of those tomorrow," reported Clive. "We don't have a league game next week so hopefully in the time we have they can both get themselves fit."
After a sluggish beginning, Clive Allen was happy with the way our Reserve side seized the initiative against Reading on Wednesday evening.
