The Gunners battled back to win 2-1 in their Champions League opener, with Wenger serving the first of his three-game touchline UEFA ban.
Bould said afterwards: "I am not sure I enjoyed it. I have got a headache and a half.
"It is tough, a different pressure than I have been used to taking the Under-18s - but we won and we had a great result."
Bould felt it was another encouraging display from the squad.
"It was difficult. I thought we were excellent in the first half - we kept the ball and kept the crowd quiet," he said.
"We looked a little bit tired in the second half, because it was very humid and the crowd got behind them. It is quite an intimidating place to come and play so we are glad to get the result.
"We have had a decent start to the season and we have kept the run going so it's important all round, for the whole season.
"We have got great team spirit and I think that was evident tonight. Everybody is digging in and things are looking okay."
