Liverpool captain Steven Gerrard has called on boss Brendan Rodgers to strengthen the squad after a strong end to the season.
The Anfield club lost only two of their final 16 league games yet still found themselves 12 points behind the top four, and two points behind Merseyside rivals Everton.
Liverpool have shown improvement under Rodgers, finishing one place and nine points better off than last season.
Gerrard has been impressed with his his teammates in recent months, having taken 30 points from 16 league matches since defeat at Old Trafford in January.
He said: "Since January this time has shown a better level of consistency. We've shown Champions League form and there is a lot of optimism and positives to take into next season."
Despite the excellent end of season form, Gerrard admits Liverpool fell short of their targets and further improvement under Rodgers is necessary.
"Our target at the beginning of the season was fourth (place) and we have not delivered that - as players we need to take responsibility for that," he added.
"We finished seventh finished seventh in the league so there certainly needs to be a bit done."
Gerrard feels the Reds could fall further behind without improvements being made to the squad, but has faith in his manager to make the right decisions this summer.
"All the other teams will strengthen and we can't afford to be left behind," concluded the England star.
"I am sure the manager is already thinking about thinking about he needs to strengthen the squad to make up that gap so we compete with top four."
If Liverpool are to compete for the top four next year they'll have to do so without Jamie Carragher. The defender played his final game for the club before retirement in Sunday's 1-0 win against QPR.
