Allen was benched in Liverpool's games against Stoke and Fulham before making a return over the comprehensive 3-0 win against QPR over the weekend.
The former Swansea player insists that he is feeling on top of his game after the mini-break and is ready to nail down a spot in the first eleven for the Reds.
"I am feeling good. Obviously I wasn't involved too much in the last couple of games, which has given me a little bit of a rest," he said.
"Hopefully it has freshened me up for that game.
"It is a massive privilege to play for this club so I enjoy every minute of it."
Liverpool will host Sunderland on Wednesday evening and Allen is wary that the Mackems will pose a serious threat to the Reds despite hovering four points above the relegation zone.
"Sunderland have had three wins in their last five games and really picked up.
"Obviously they beat Manchester City at home, which will have given them massive confidence, and we'll have to be at our best.
"We drew away from home when we played them so we will be hoping to get all three points when they come to Anfield."
