Allen has enjoyed some of his best form in the second half of the season.
The Welsh midfielder has been used from the start when Klopp has rotated his side, but he has also been used from the bench when Klopp has gone full strength.
Some have said that Allen has enjoyed the best football of his Liverpool career since January as he looks to earn a new contract at the club - with his current deal expiring at the end of next season.
Allen is quoted from the official Liverpool website, saying: "I think things have gone pretty well for me recently and I’ve probably had more game time now than in other parts of the season, which has been great on a personal note.
"I think you always build momentum when you’re part of winning team performances."
Allen was something of a maligned figure under Brendan Rodgers but his recent displays have earned him a lot of respect from Liverpool fans, and there was a clear desire during Wednesday's Merseyside derby to see him on the scoresheet as the Reds swept their neighbours Everton aside in a 4-0 win.
He added: "That reception they’ve given me in the last couple of games has been huge for me.
"I’m really grateful for the support they’ve shown me as an individual. I’m hoping, given the chance, I can reward their support with some good performances."
It remains to be seen whether he will be offered a new deal at the club, but manager Jurgen Klopp seems to want to discuss his future in the summer.
A lot may depend on whether Allen is satisfied with the role he has at the club, whether he likes being the man that will come in and fill in for the odd game in order to keep the side fresh, and be part of the much changed side that might need to beat sides lower down the table in order to keep them in touch at the top.
If he stays fit, it's still a role that could see him play in excess of 30 games a season.
