The 21-year-old completed a £15m move from Swansea City to Liverpool earlier this month but the Wales international’s Reds debut ended in a 3-0 loss at the Hawthorns.
However, Allen is looking forward to making his first appearance in the Europa League against Hearts, before appearing in front of the Anfield faithful when Premier League champions Manchester City make the trip to Merseyside.
“It could be a very special week for me, getting the chance to play in Europe for Liverpool and then hopefully my Anfield debut against Manchester City, and we hope at the end of both of those games it will be a nicer feeling,” Allen told Liverpool’s website.
“We will certainly give everything we have got for our supporters.”
Goals from Zoltán Gera, Peter Odemwingie and Romelu Lukaku completed a memorable victory for Steve Clarke’s West Brom side on Saturday – and Allen insisted Liverpool must to move on quickly from the result.
“They scored a fantastic first goal and that was one when sometimes you have to hold your hand up and say it is a great goal and there’s not much we could have done to stop that,” he added.
“The first goal certainly gave them a foothold in the game and then with the decisions that went against us, and going down to 10 men, it changes everything.
“Throughout the season there is going to be some days like this and we will regroup, work hard in training and get ready for Thursday’s game.”
