Jurgen Klopp has warned his players to buckle up and give their best in the five weeks left before the January transfer window as he may have to invest in the market if he does not find the players at this disposal good enough for a top four charge. The manager has won only one Premier League game since taking over at Anfield and is ready to invest in order to get his team back on track.

He has been given a free hand to change the squad as he deems proper in the upcoming transfer window something he is ready to consider given the form of certain players and the injuries in the squad. The Reds are without Danny Ings, Joe Gomez, Daniel Sturridge and Jordan Henderson, with the former two unavailable for what can be the rest of the season with anterior cruciate ligament injuries.

Sturridge was out with an injury to his knee but has returned to full training ahead of a possible comeback against Manchester City this weekend. The striker has been a major miss for the Merseyside club and Klopp will be hoping that he can keep himself fit for the busy Christmas period, which could determine his side's fortunes for the end of the season.

"We will have the possibility to change some things in January and in the summer but at this moment we have made no decisions because we don't have to make them yet. The players know this. It is always the same that at one point in the season you have to make a decision about them," Klopp said, as quoted by the Mirror.

"We are at a time when they can collect positive arguments and say: 'okay, we want to work together'. I don't need to say this to them, they know it. In this moment we have made no decisions so I have time to judge.

"To make a final judgment on them I need more time. I know about the business of course. We have time and we will see what is possible and what is not possible. We will see what's necessary and what's not necessary, that's how we work," he added.
