The Serbo-Spaniard showed his ball-winning skills, was accurate in passing and nearly scored with a swerving free kick late in the first half.
Here are a few reactions to his display from Liverpool fans on Twitter.
Samuel: “Stefan Bajcetic. Remember the name.”
A.O.: “Bajcetic has set piece in his locker too. We might have a gem”
Arvid Påhlman: “Is Bajcetic the perfect footballer? He dribbles, tackles, passes and takes good freekicks. What can this lad not do?”
Biggies Malls: “Bajcetic could be another little diamond you know.”
A J: “I know this game is for bants but Bajcetic is too good not to be a part of our team next season”
Wilco: “Bajcetic is on his way to becoming a star, unreal young player”
Lewis: “Bajcetic is so lucky that he’s going to be able to learn from Fabinho for the next few years. You can see similarities already.”
R8: “Bajcetic might be the best tackler in the squad…”
Harry: “Really do think there’s every reason for us to be very excited for Bajcetic’s future.”
Nikz: “Bajcetic is one for the future. He’s had a good pre season. Would like to see him play a lot more especially in the cup games. Looks like he could be useful for set pieces as well.”
Taintless Red: “Bajcetic is very good at winning the ball. Just times his interceptions or his tackles. Quick response time and quick feet.”
