Despite the defeat to Liverpool last weekend the Black Cats confidence remains high after wins against Bournemouth and Hull in their previous games.
The 22-year-old, who missed a gilt-edged opportunity against Liverpool on Saturday, feels the Wearsiders must now continue their good progress when they take on the champions this weekend.
"Like any team, it helps when you are winning," he told the Gazette. "You have that momentum and the last few performances have shown that.
"When you have back-to-back wins in the Premier League it helps, it’s a shame we couldn’t do it at Liverpool.
"Back-to-back wins showed we are clicking and we’ve got to make sure we show that it’s not a one-off and we move forward and we carry this on."
