Munich - FC Bayern München welcomed Alek Skarlatos, the off-duty US Air Force officer who heroically thwarted a terrorist attack on a train travelling from Amsterdam to Paris last week, to their Säbener Straße training complex on Wednesday.

Skarlatos was one of three men, all childhood friends, to have received worldwide recognition for their intervention. President Barack Obama, updated on the attack Friday night, "expressed his profound gratitude for the courage and quick thinking of several passengers, including U.S. service members, who selflessly subdued the attacker," a White House official said. "It is clear that their heroic actions may have prevented a far worse tragedy."

'Magnificent guys'

The heroic trio were awarded the Legion d’honneur by French President Francois Hollande for their incredible act of bravery. Skarlatos was later photographed proudly showing off his medal in a Bayern shirt with Müller's name on it, which prompted the record German champions' surprise invite.

"These guys are heroes," tweeted Bayern forward Thomas Müller on Monday, before getting to meet Skarlatos in the flesh. "And one of them was wearing my shirt. Magnificent guys." The moment was naturally caught on camera and created quite a buzz on social media.
