Aspas completed a £7.7million switch to Anfield from Celta Vigo in the summer, and was tipped for big things by manager Brendan Rodgers after an impressive pre-season, which saw the Spaniard hit the net three times.
The 26-year-old started the first three games of the season, before coming off the bench in the second half of Monday’s 2-2 draw with Swansea.
And Aspas has admitted he is not currently enjoying life on Merseyside after his failure to find the back of the net.
“Over the last four or five seasons I haven’t gone as many games as this without a goal,” Aspas told Liverpool’s website.
“I’ve never been an out-and-out goalscorer but it’s true that over the last three seasons I have scored quite a number of goals.
“I suppose on a personal level I’m not entirely happy as I would want to be because I still feel I can do better.
“I’m working hard every day to improve and to be able to show that on the pitch to my team-mates.”
Aspas is set to get another chance to break his duck tomorrow against Southampton, especially since Brazilian playmaker Phillipe Coutinho has been ruled out for six weeks with a shoulder injury.
And while the forward is not satisfied with his own form, he still believes this campaign will prove a positive one for the Reds.
“What I have done is aimed at playing as many games as possible and to try and help the team to get into the top four, which I think is the most important thing for us,” he added.
“It’s all about focusing on the group as a whole in order to qualify for the Champions League.”
