If they’re sensible, the approximately 472 full-backs Mohamed Salah has eviscerated over the past decade will spend the next few months watching this match back on replay.

Because Nuno Mendes, the PSG left-back, contained the Egyptian in a manner very few have.

On the few occasions Salah threatened to get in behind, Mendes matched him for pace and cut out the danger. When Salah tried to skip inside and create, Mendes — often with help from Fabian Ruiz — hassled him.

More than anything, Mendes simply displayed huge powers of concentration and diligence, sticking to his man like glue throughout. Salah’s exit, four minutes before the final whistle, spoke volumes.

For Mendes though, the night was not quite over. In a cruel twist of fate, he failed to properly track Elliott — Salah’s replacement — in the dying stages and had a perfect, painful view of the goal.

It soured what had, up to that point, been a sterling individual display.
