Liverpool manager Brendan Rodgers will target "multi-dimensional" signings in the summer as he looks to bolster his squad for the Champions League.

The Reds are back in Europe's elite club competition for the first time since 2009 after finishing second to Premier League champions Manchester City this season.

However, the playing resources are in serious need of strengthening if they are to compete on two fronts and Rodgers is looking at some significant re-shaping of the squad.

He has already targeted Saints and England midfielder Adam Lallana as a priority - slapping in a £20m bid which has yet to be publicly acknowledged by Saints - and he is interested in Sevilla's Europa League-winning left-back Alberto Moreno.

"Our criteria that we look for is players with strong technique and football intelligence," said the Reds boss after their 4-0 friendly victory over Shamrock Rovers in Dublin last night.

"They need to mentally have the attitude and the capacity to learn and they have to be so hungry to fight for every ball on every day in training and in the game.

"You'll get some players who are specialists and who need to play in particular positions, but if we can get players in who are multi-functional, and can play in different roles and are multi-dimensional in their work, it sets us up and gives me more options as a coach.

"We've developed tactically over the last couple of years.

"Our style has been the same, but the structure of the team has changed a number of times in order to fit the needs of the games and to give problems to the opponent.

"In order to do that, you need players with the capacity to be tactically intelligent. It also allows you to keep your squad smaller and tighter."

Liverpool banked over £97million from the Premier League prize fund and television money this season and Rodgers could have between £40million to £60million at his disposal in the summer if he offloads a few unwanted players.
