Liverpool cruised to a 4-0 win over friendly opponents Borussia Dortmund yesterday.
Daniel Sturridge opened the scoring after 10 minutes and Dejan Lovren doubled their advantage three minutes later as Brendan Rodgers' side took control early on.
Philippe Coutinho added a third in the 49th minute and Jordan Henderson completed the scoring just after the hour mark.
"Of the two boys that played today, Dejan was perfect - he's what we've been looking for since Jamie Carragher left. He's a very dominant centre-half," the Reds boss said.
"He'll go and attack the ball, reads the game incredibly well and you can see his leadership qualities with his talking and guidance of the back four.
Three and easy: Coutinho bagged Liverpool's third after the break
"You also saw his range of pass on both sides, left foot and right foot. His pass into [Philippe] Coutinho for the first goal was wrapped in with his left foot and that creates the nick around the corner to get us the goal.
"Like he showed us last year, he is dominant in the air in the other box, attacking it. I thought he was excellent.
"And young Javier Manquillo was outstanding, at 20 and playing his first game at Anfield having only joined this week. His fitness level was very good.
"He's the type of full-back I like - he can get tight to people, stop crosses and defend well, but also then has the energy to attack and get forward. He was very, very good."
