Liverpool have made an offer of between £8m and £10m to Southampton for striker Rickie Lambert, Sky sources understand.Earlier in the day, Liverpool boss Brendan Rodgers said 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 next term, 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."
