It just shows that the very best players are capable of winning a match single-handed. Benzema made all the difference here, and it will go down in history and Real folklore as one of the epic individual performances, twnety minutes and three goals that completely transformed the tie.
Talking of how it just takes one brilliant individual to turn a match around, who did PSG have up front? Messi. Mbappe. Neymar. Any of them should be capable of the same. But it's just not working out, that's their season gone now, really. All that's left is the league, which they've effectively won already. Nothing to do until next year, and another try at the Champions League. I'd be surprised if they have the same front three then.
