Sergio Aguero takes part in Argentina training ahead of World Cup final, he scored a rocket

Sergio Aguero scored and even saved a penalty when he took part in Argentina training ahead of Sunday's World Cup final against France – and it's so good to see him back on the pitch.

The 34-year-old former Manchester City and Barcelona forward announced his retirement from professional football last year after being diagnosed with heart arrhythmia.

Months later and Aguero was expected to join Argentina's coaching staff at this winter's World Cup, but he eventually decided against helping coach the team.

"The invitation to be part of Argentina staff was in the table. I spoke with Chiqui [Tapia, Argentina Football Association president] and I was clear with him about my goal to enjoy my time," Aguero told ESPN. "I'm going to Qatar, but as a fan."

Things didn't get off to the best of starts in Qatar for Aguero, who got stuck on a plane full of Brazil fans before landing in the Middle East last week to support his former teammates.

He was then prevented from entering the grounds after being told that the correct accreditation could not be arranged in time.

Aguero, who criticised his country's football association [AFA] after being denied entry, eventually managed to get access and ahead of this Sunday's World Cup final, he was invited to train with the squad.

After doing a light warm up on the bench, he eventually took part in some shooting drills at the Qatar University training site 3.

He even went in between the sticks before saving a penalty. You can see that moment below.

Aguero continues to be Argentina's biggest supporter at this winter's tournament. He even greeted former roommate Lionel Messi after his masterclass against Croatia in Tuesday's semi-final.

After leaving the dressing room, Messi's face lit up when he saw his friend with the Player of the Match prize in hand. They embraced before the Manchester City legend handed over the trophy.

It was a moment that sums up their special friendship.

"They played a very calm game, they waited for the moment," Aguero said after the Croatia game. "Because Argentina, until the first goal, didn't press as much, and they had possession but they didn't do much either.

"I think that after the 2-0 Croatia were already tired. They fell apart."

Do you think Argentina can lift the World Cup this weekend?
