PSG practiced penalties...just in case

 While Luis Enrique did not want to considerate a possible round of penalties, Emery had his players training hurls before traveling to Barcelona.

There are spirits of coming back in at Barcelona and it seems that PSG is not so sure about a victory any more. It seems like Emery wanted to hedge his bets and trained particularly penalties with his players before leaving to Barcelona.

Emery is an perfectionist and prepares every match into the last detail, this is why he wanted to have all the chances covered. Quite the opposite is Luis Enrique who did not care too much about this possibility.

For penalties to happen, Barcelona would have to score 4-0 against the Parisians and the extra time would have to end without any goals. It does not seem easy, but PSG is prepared for the worst-case scenario.
