Martin Skrtel admits Liverpool's 2014/15 season was well below par and is determined to improve for the upcoming campaign, reports the club's official site.
The Reds finished a lacklustre sixth in the Premier League and also crashed out of the Champions League in the group stages. Brendan Rodgers' key aim for the year was to add a piece of silverware to the Anfield trophy cabinet, however Liverpool were knocked out of both the League Cup and FA Cup in the semi-final.
After splashing the cash on new recruits last summer, including Dejan Lovren from Southampton, Liverpool could not build on their almost title-winning campaign of 2013/14, despite their being so much promise heading into the new season.
Rodgers' squad meet up at Liverpool's Melwood Training Ground on July 6 to begin pre-season training were new recruits such as James Milner and Joe Gomez are set to join their new team-mates before heading to Thailand for a pre-season tour.
And Skrtel cannot wait to get back on the training field and begin preparing for next term.
"When you lose or have a bad season it's an awful feeling," the Slovakia international told Liverpool FC's official magazine.
"You are sad and disappointed and you don't really want to speak to anyone. I don't kick a wall or shout but it stays with you for a long time.
"I always try to look at why we lost or why I didn't perform well. I think you have to do that because you need to see why something happened.
"And I know the only place you can change it is out on the training field, so you have to work hard there to improve."
After failing to qualify for the Champions League, it's likely that it will be Liverpool's key aim for the upcoming season.
Rodgers has kept his job as manager despite his assistant Colin Pascoe and head coach Mike Marsh being let go by club owners Fenway Sports Group and there will be significant pressure on the Northern Irishman to deliver results.
The summer arrivals at Anfield have already been extremely positive as the Reds look to start the season with a bang, as opposed to last year when they took just 14 points from their opening ten games.
Milner rejected Champions League football to join the Merseyside outfit and his presence will give Rodgers plenty of options in the centre of the park and replace Steven Gerrard, who's moved to Major League Soccer side Los Angeles Galaxy.
Roberto Firmino has cost the club £29 million, their second biggest transfer in history, and he looks the replacement for Raheem Sterling who looks destined to move to Manchester City in the coming weeks. Firmino has been impressive at Bundesliga side Hoffenheim, but, there will be plenty of pressure on the Brazilian to deliver early.
