Chambers now hopes that Arsenal can continue their recent form and enjoy a strong finale to the season.
"Getting a clean sheet is always a positive for us defenders and for the whole team," he told the club's official website. "We knew it would be a tough game because West Ham are a good side but I thought we played well, kept strong and got the goals we needed.
"We've got a lot of confidence and we're building momentum in the league. We're getting a lot of good results and we've just got to keep the positive vibe and keep getting the results we need."
Arsenal are back in Champions League action on Tuesday when they will try to overturn a 3-1 first-leg deficit away to Monaco in the last 16.
