Gerrard featured in the first-half of the 2-0 win.
"I thought that all the new lads did well tonight," Gerrard told LFC TV . "I thought [Mignolet] was fantastic with his feet and he did everything well.
"Toure looked assured at the back and was very vocal. People are talking about missing Jamie [Carragher] and Jamie's voice, but I thought Kolo led from the back tonight.
"The two Spanish lads, as I said earlier in the week, are wonderful technicians on the ball. Aspas works his socks off for the team and you can see Alberto's quality. That's what we bought him for - to play against sides where it's difficult and you need someone to unlock the door.
"They're the magicians who are going to unlock the defence. I'm really pleased with all the newcomers tonight."
