'I'll kill you in the street' - Mbappe threatened Alba in PSGs 4-1 win over Barca

Hat-trick hero Kylian Mbappe was said to have threatened to kill Barcelona defender Jordi Alba on the street during Paris Saint Germain's 4-1 Champions League triumph at Camp Nou.

The Frenchman hugged the headlines after outshining Lionel Messi and his teammates to score three stunning goals and handed PSG an advantage ahead of the second leg in Paris next month.

However, the World Cup winner had a heated argument with the Spanish defender in the almost one-sided game as other teammates quickly moved to separate the two stars from clashing.

Mbappe was initially caught on camera by a TV station Movistar telling Sergino Dest to stop touching him while the visitors were awarded a free kick in the first half.

Alba heard their conversation and told the PSG forward to 'get bigger' but the forward didn't take it likely as he threatened to kill his opponent on the streets according to Daily Mail.

The PSG attacker then replied in perfect Spanish:

"I will kill you in the street. I will kill you in the street."Centre-back Pique then backed Alba up by telling Pique,

"Who are you going to kill?" Alba then joked, "He's learning, he's learning."

Mbappe ended up winning the man of the match and also the match-day ball for inspiring PSG to a 4-1 triumph over the Catalans in the encounter.

Mauricio Pochettino's men are now one step into the quarterfinals of the Champions League as they have four away goals from the first leg earlier this week.
