"It was obviously a very big test, a very big hurdle and obstacle for us to overcome. I thought we did that extremely well," he told BBC London 94.9.
"David Mooney's form has been remarkable and his performance today was excellent, but it would be very difficult and unfair for me to pick out one player today.
"I thought as a team we looked very solid, very resilient and a threat going forward."
The win was the O's sixth away from home.
