Full-back Briggs, 19, impressed in last week's 1-0 defeat at Chelsea and despite finding himself back on the bench for Saturday's goalless draw at Newcastle, he was encouraged.
"It's a massive leap for me," he told his club's official website. "I've got my foot in the door and I've got to keep it there now. I've just got to prove myself.
"From playing against Millwall reserves to playing against the champions was a big step and the pace of the game was a lot quicker.
"Playing against the likes of (Didier) Drogba and (Salomon) Kalou was a big challenge. The players all told me that I did well so I've got to take that on board and move on from there."
