Former Liverpool player Jan Molby believes Jurgen Klopp must strengthen his squad if they are to secure Champions League qualification.
The Reds brought in seven players in the summer transfer window as part of a substantial overhaul of their squad but have been beset by injury problems, with the likes of Daniel Sturridge, Jordan Henderson and Danny Ings yet to play a single match under Klopp.
Liverpool dropped to 10th in the Premier League table after suffering their first defeat under Klopp against Crystal Palace at the weekend, but Molby believes the German needs to bring in his own players before he can be properly judged.
"I'd like him to do business in the January window because there's everything to play for," Molby wrote in the Liverpool Echo. "Even when you're winning titles there will be games and afternoons like Palace and I think Liverpool's only target for this season – the top four as I understand it – remains full on.
"For Klopp as a new manager he'll instantly have identified something he can improve upon – he'll be thinking 'we're missing this and I know where to go to get it'."
Molby believes Liverpool can benefit from Klopp's intimate knowledge of German football, with the 48-year-old having coached Mainz and Borussia Dortmund in the Bundesliga before arriving at Merseyside. "There's nothing wrong if he wants to go back to Germany, Jurgen should work in the market he knows best," the former Reds midfielder stated.
"He's a fan of a strong running game and that's something you get in the Bundesliga so the players from there will be used to that already."
Klopp has completed one month in charge of Liverpool and has overseen three wins, three draws and a defeat in his seven games in that period. Molby said the German had made a solid start in English football.
"I'd give him a 7/10 so far," he said. "I think we had an unbeaten run at the end of the Brendan Rodgers era but I think we now look like a team that could win more games and perhaps go on a run of wins."
