Liverpool midfielder Allen stronger for full preseason
The Wales international's London Olympics' involvement last summer disrupted his season preparations.
"It has been different. Obviously I've had the chance to have the full pre-season this year because I missed the tour last year (having signed just a week before the new season started)," he said.
"I got a goal and things went quite well on Saturday, although I missed a couple of chances.
"I'd like to think there are a couple of positions I can offer something in so when I get my chance to play whatever position I need to show I can perform and do the job.
"There is massive competition for places in the squad and that is what you want as it as it always brings out the best in everyone.
"You know if you are off your game slightly there is someone waiting in the wings to take your spot."
