Liverpool have been told they must dip into the transfer market in January or risk derailing their season.That’s the view of former Reds midfielder Jermaine Pennant, who pointed to right-back as a particular concern.Liverpool won the league under Slot when they spent very littleGettyArne Slot splashed out £450m on transfers in the summer after winning the Premier League title.What was predicted as a runaway season to retain their title has not worked out.Slot’s side are 14 points off leaders Arsenal in a run that has included nine defeats in 12 games in all competitions.Liverpool have surprisingly been found lacking in plenty of areas of the pitch with Mohamed Salah suffering a decline in form, Alexander Isak struggling and suffering a serious injury, while right-back has been something of a problem since Trent Alexander-Arnold’s move to Real Madrid.The issues in defence have been compounded by Conor Bradley’s season ending injury in the 0-0 draw with Arsenal.Jeremie Frimpong has at times been utilised further up the pitch in Salah’s absence at the Africa Cup of Nations.Outside of Frimpong, the only recognised defender that can fill in there is the injury prone Joe Gomez.Reports claim that Liverpool will not look to bolster their defence in the January window.talkSPORT’s Inside Liverpool YouTube show gave their verdict on the news.Pennant said: “I’m very disappointed in hearing that Liverpool won’t be signing a right-back, to not even look at maybe a loan option… if you don’t want to spend money fair enough.Bradley is set to be out for the rest of the seasonShutterstock Editorial“We spent quite a lot in the summer, but some sort of cover, maybe someone who can even just sit on the bench.“We are injury prone at the moment and down to bare bones and loads of games coming. We are still in loads of competitions and have got to try and maintain to keep in the top 4 for Champions League football.“It’s a little bit disappointing and as the hierarchy, the sporting director and the board should be looking at this thing if we don’t get anyone in we are taking a gamble.“If we get one more injury that could really destroy our season in every way shape and form. It’s disappointing to hear that we are not looking at getting anyone. I don’t know how they can sit there and go ‘yeah everything is fine it’s alright’.”Marc Guehi move?Guehi’s move to Liverpool collapsed on deadline day in the summer after Crystal Palace manager Oliver Glasner threatened to walk.The England centre-back is out of contract in the summer, where he will have the pick of his destination.Guehi has been a long-term Liverpool targetGettyMan City could make a jump on the field by trying to sign him this month amid their defensive injury woes.Liverpool, however, are unlikely to rival City in January.Former boxer and huge Liverpool fan Paul Smith said: “Speaking about Marc Guehi, if we’re not playing well and City are who are you going to choose? Especially if they’re going to offer a bit more money.“Secondly, I’m not the expert, but if I’m the owner I’m thinking I’ve just given you £450m. Why would I want to give him any more? We might be thinking about getting rid of him and replacing him with a different manager.“Let’s save it for when the new manager comes in or if the new manager comes in.”Listen to the latest episode of talkSPORT’s Inside Liverpool show on YouTube.
