Liverpool manager Brendan Rodgers maintains the club are working hard on making further summer signings despite stalling in their attempts to add to their four earlier additions in the window.

Kolo Toure, Luis Alberto, Iago Aspas and Simon Mignolet were signed in the early weeks of the transfer window, with Rodgers immediately stating his intention to make further signings with an attacking midfielder and a left-back on his wishlist.

But Liverpool have been unable to make another significant foray into the market and Rodgers admits further signings can improve Liverpool's fortunes this season

"There's a lot of work going on behind the scenes. Obviously it's not easy," Rodgers said.

"We have seen that from other clubs' experiences as well. But I'm confident we will add to the team. I don't think there is any doubt that we need that.

"The players that we've brought in have added great depth and support to the team, but I think for us now, that little bit of quality could really set us up for an exciting season.

"Everyone at the club, the recruitment team, the board and ourselves, we are all working hard to make that happen, and hopefully we can.

"There's money there available to get in the right types of players, but we don't want to panic and just bring in anyone. It has to be someone who can come in and improve the team."

Rodgers and managing director Ian Ayre could be forgiven for being distracted by the future of Luis Suarez which looks no closer to being resolved with the Uruguyan reportedly unwilling to apologise for media comments suggesting the manager had lied about allowing him to leave this summer.

Owner John W Henry has already stated that Suarez is not for sale at this late stage of the summer with not enough time available for Liverpool to secure a replacement.

Daniel Sturridge remains out with an ankle injury and with Suarez at a stand-off with The Reds hierarchy, Aspas and Fabio Borini, whose first campaign with Liverpool was disrupted by injury and inconsistent form, are likely to lead the attack in the opening weeks of the season.
