Many have criticized Liverpool performance in the first leg, and I agree that they were lucky to win. Alisson Becker was impressive, he denied many PSG chances, in my opinion it was his best performance of the season. I am quite sure that luck will be on PSG side in the second leg if Arne Slot does not change his squad game strategy, considering that Luis Enrique is very experienced in reading his opponent's weaknesses. Given the ambition of both teams, it is likely that both will be able to score goals.
I agree with you about how Liverpool played firstly. They did win but they were also lucky at times. Alisson Becker was best player making some very important saves to stop PSG from scoring. However I do not think Liverpool will be as lucky next. PSG has very good team and smart coach in Luis Enrique who will try to find weaknesses in Liverpool plan. But Liverpool has shown many times that they can play well in big games. I think you are right that both teams will score goals which will make second game very exciting. It is going to be very interesting match.!
PSG performance must be admittedly very troublesome so that Arne Slot did not have many choices other than instructing his players to defend totally and only rely on counter-attack opportunities. In my opinion Liverpool seemed surprised because PSG resistance was beyond expectations by launching more than 25 shots on goal which kept Alisson busy for 90+ minutes. The single goal was actually very lucky because we saw that during the first half and the second half PSG never lowered the intensity of the attack. In the second leg Liverpool will give their answer to PSG and Arne Slot want to make a counterattack at Anfield.
