Liverpool manager Brendan Rodgers has revealed that he is looking to bring in more players before the transfer window shuts down on 1 September.

The Reds have shelled out nearly £90m to sign Rickie Lambert, Emre Can, Adam Lallana, Lazar Markovic, Dejan Lovren and Divock Origi. Having strengthened attack as well as the midfield, Rodgers wants to bring in defensive reinforcements to curb last season's frailties that denied them the Premier League title.

The Merseyside club are believed to be closing in on double deals for Spanish fullbacks Alberto Moreno and Javier Manquillo, which will shoot their summer expenditure beyond the £100m mark.

The 41-year-old wants to improve his squad's depth in order to maintain the overall fitness of his players; given the increased number of fixtures Liverpool will be playing next season.

"We still have some positions that we want to fill within the squad so that by the end of August we have a strong group of players to go forward with. We've still got some business to do," Rodgers told Liverpool's official website.

Out of Liverpool's six summer signings, Origi will not play next season as he returned to Lille on a season-long loan. Lallana is unavailable for five weeks more due to injury while Lovren could be in action for the first time when Rodgers' side face Borussia Dortmund in a friendly at Anfield on 10 August.

The former Swansea City boss also gave an update regarding how his summer recruits are getting along with the current players before the start of the season.

"We've brought in specific players for specific roles, players that have the profile of how we work. It's going to take a little bit more time than normal in terms of their induction," Rodgers explained.

"But for a lot of the players that have come in, the transition has been very smooth - they are good characters with good personality and fit the criteria that we want in terms of the model of our game."

"That should make the adjustment that bit easier. Of course some of them are young and coming to a different country, like Emre Can. That will take a little bit of time," the Northern Irishman added.

"But what we have seen overall is something that has been a trademark of this team over the last 18 months - character. Even in a pre-season game, it was highly competitive and the players showed character to keep going and come back."

"They made some very good blocks and defended well. It was a really good game. The players are transitioning very well, though it will take a little bit of time," he concluded.
