Darwin Nunez looks set to start up front alongside Mohamed Salah for Liverpool's clash with Southampton.
Salah, who is not going to the World Cup in Qatar, will play alongside Nunez up front with Firmino in behind. Klopp is looking for more signs of a developing relationship between Andy Robertson and Nunez on the left flank, and the German has called for the Uruguayan to work more on his defensive role.
“We know Darwin can be a real threat offensively but defensively there is room for improvement,” said Klopp. "We don’t want to talk to him all the time about defending and all of a sudden he forgets to attack so we want to give him the freedom to feel like a striker.”
