2 Right-backs:Rumours have been quiet bar a link to USA defender DeAndre Yedlin, who shone at the World Cup. Speculation has indicated he will link up with the Reds for a trial during their pre-season tour of the States. But with more pressing concerns in other positions it appears Rodgers may put his faith in Johnson and Flanagan despite the reservations of supporters.ATTACKIt’s no secret why Liverpool need to seek immediate reinforcements here. Last season they thrilled fans up and down the country with their gung-ho attitude led by the devastatng Luis Suarez. But with the main man gone and the replacements brought in so far lacking his level of stardust, there remains work to be done. Current options:There is certainly no lack of options up front and many believe that Daniel Sturridge will now relish taking on extra responsibility in the wake of Suarez’s departure.In support he will have the likes of Loic Remy, who is set to sign for £8.5m and Rickie Lambert as ‘out-and-out’ strikers. Raheem Sterling and Lazar Markovic will offer support out wide, while Adam Lallana and Philippe Coutinho can offer creativity behind the front three.None of them possess the world class talent of Suarez, though. There is a feeling that while the Uruguay star is irreplaceable, Liverpool need a marquee signing.The targets:They missed out on Alexis Sanchez, but Borussia Dortmund’s brilliant forward Marco Reus has been linked with a move to Anfield and that will certainly get supporters eagerly awaiting the new season.Despite operating mainly from the flanks, Reus has netted 42 goals in 90 appearances for Dortmund and boasts seven goals in 21 Germany caps. The 25-year-old was a key part of Joachim Low’s squad in the build up to the World Cup but was cruelly denied a spot in Brazil by injury. He might not be Suarez but Reus certainly has world class talent and would bolster Liverpool’s frontline immeasurably. Liverpool boss Brendan Rodgers 2 2 Transfer window verdict: 7/10 Had Liverpool kept Luis Suarez many would be singing the club’s praises for a pro-active approach to the transfer market. They have brought in well established Premier League players such as Adam Lallana and Rickie Lambert, while the imminent arrivals of Loic Remy and Dejan Lovren also boast experience on these shores. New boy Emre Can looked classy on his debut against Preston in pre-season despite picking up an injury and another arrival Lazar Markovic starred for Benfica last year. However, all of this pales in comparison to Suarez’s importance and his exit combined with a lack of defensive additions means Brendan Rodgers needs to continue scouting the market for more recruits. Liverpool manager Brendan Rodgers has been attempting to build a big enough squad to handle Champions League football and challenge for the title again.Here, talkSPORT looks at the transfer business so far and assesses where there is still room for improvement.Who they’ve signed:Adam LallanaRickie LambertLazar MarkovicEmre CanWhere they need to strengthen:DEFENCEBoth full-back positions leave a lot to be desired and Rodgers is in dire need of finding some fresh faces.Current options:Right-back Glen Johnson proved at the World Cup he is never going to be dependable enough and he could be easily found out in the Champions League, meaning an upgrade should be considered a necessity.On the left, Jose Enrique’s pedigree is more difficult to assess after his season was ravaged by injury. Jon Flanagan – typically a right-back – deputised brilliantly in an uncustomary position but if the Spaniard cannot prove his fitness, persisting with the young England man is not a viable option if Liverpool want to challenge for honours.The targets:Left-backs:Sevilla are driving a hard bargain over Alberto Moreno while Swansea’s Ben Davies is set to reject Anfield in favour of an £8m move to Tottenham.However, there are other targets such as Ajax and Netherlands star, Daley Blind and Chelsea’s Ryan Bertrand. Manchester United and Barcelona are known admirers of the former but if Rodgers could beat them to the punch, it would send out a real statement of intent. Meanwhile, the latter has shown flashes of potential during his time at Stamford Bridge and could benefit from working with a manager not afraid to trust in young talent.
