Kylian Mbappe is already back at PSG training after World Cup final heartache, his mentality is elite

Kylian Mbappe may have lost a World Cup final he scored a hat-trick in, but he's already back in training for Paris Saint-Germain.

The final on Sunday looked to be going quite easily to Argentina for the opening 80 minutes, as Lionel Messi and Angel di Maria' goals in the first half and a controlled performance from the South Americans looked to have been enough.

However, with just 10 minutes to go Mbappe sprung into action and scored twice in quick succession to take things to extra time.

Messi scored his second of the game in the additional 30 minutes only for Mbappe to become the first man in 56 years to score a hat-trick in the World Cup final and take it to penalties.

Sadly for the Frenchman it wasn't to be enough, with Emiliano Martinez's sh**housery coming out on top in the penalty shoot-out.

You'd understand if Mbappe just wanted to lock himself in a dark room and not come out for a while, even if he has already won the World Cup before.

He won the Golden Boot at the tournament but losing it in such circumstances must have hurt, especially when it was to club teammate Messi.

Worse still for him, he's been mocked by Martinez, and Argentina fans, during the winners' trophy parade back home in Buenos Aires.

Despite all that, the 24-year-old, whose birthday was two days after the loss, has already turned up for PSG training.

According to reports, he was meant to have around 10 days off before he was back in training but he decided to return to the club early.

That means in roughly 60 hours he's gone from losing the final in Qatar, returning to France, celebrating his birthday and then heading back into work.

It certainly means that the forward could even be in action in just a week's time, when Christophe Galtier's side pick up their league campaign.

The French champions currently sit at the top of the table, five points above closest challengers Lens by five points, and take on Strasbourg on December 28th.

It's unlikely that Messi will be back in time to play in that game, he's currently too busy struggling to get into his home in Argentina.

Mbappe's example is certainly one to follow for younger players, and it's not the first time he's shown such leadership qualities.

A video from half-time in the final, with his team two behind, showed how passionate he is for the national team, giving an emotional speech to his teammates.

It very nearly worked out, with an inspired comeback from Didier Deschamps' team just falling short in the end.
