The German boss opted to use a four-man attack with Luis Diaz, Diogo Jota, Darwin Nunez, and Mohammed Salah in a bid for a different approach and it worked well for the Reds.
Trent Alexander-Arnold gave Liverpool the lead through a well-struck free-kick in the 7th minute. Then in the second half, Salah scored from the spot after Luis Diaz was fouled in the box.
Despite failing to score from open play, Klopp was impressed with the display of his attacking quartet. Darwin Nunez particularly should have got on the scoresheet, but he could not get the better of Allan McGregor.
“The way the boys moved up front today together I thought was extremely, extremely good for only one session working on it, to be honest,” Klopp told Liverpool’s website.
“We never did it before, we had now one session with a low intensity because we only played recently. So, you just see how good a striker [Nunez] is to be constantly in these situations. I think everybody saw tonight that this [scoring goals] will happen, so all good.”
Liverpool are second in Group A with six points in their first three Champions League matches.
They face league leaders Arsenal this weekend at the Emirates.
