Rickie Lambert is expected to undergo a medical at Liverpool on Saturday after an initial £4m fee was agreed with Southampton.And Ian Rush believes Liverpool boss Brendan Rodgers will be looking to reinforce 'every department' of their squad in the summer transfer window. The Liverpool goalscoring great told Sky Sports: "With the Champions League, I am sure they will be looking at every department to strengthen. "What do you do if Luis Suarez or Daniel Sturridge gets injured? "It also depends on who is available at what price. I am sure Brendan will be looking at every angle. "Brendan will have his people in mind. They scored more than 100 goals and had a fantastic season but let a lot of goals in. "Defensively, they have got to be looking to try and stop those goals going in. I am sure Brendan will be looking at a lot of set-pieces where they lost goals. "I think, defensively, maybe they will be looking to strengthen and maybe in midfield, as well. "When you look at the goals scored, more than 100 goals, you cannot fault them for much." Rodgers said on Thursday that he does not envisage signing any players on loan again this summer. Since taking charge at Anfield, Rodgers has regularly dipped into the loan market to bolster his squad, with the likes of Nuri Sahin, Victor Moses and Aly Cissokho all spending time on Merseyside. But now, with a UEFA Champions League campaign on the horizon, Rodgers does not believe loan signings will be beneficial to his squad. "I would hope we don't have to go for loans this summer," Rodgers told the Liverpool Echo. "But it's always about the availability of players. If you are not satisfied with the squad and you feel you can improve it, then you have to look at every option. "In these first couple of years I've been here, we have had to do that as we've had a thin squad. "The players we wanted we couldn't get but we're hopeful that this summer will be different. We turn the page and it's another chapter in terms of where we are going. "Hopefully that will mean it will be more permanent players than loan players but I can never rule it out completely. There could be a situation where a player becomes available, we can get him and he can add to what we're doing."
