Gianluigi Buffon could be playing in his final match for Italy this evening.Let that sink in.The 39-year-old will be desperately hoping his Italian side can overcome their 1-0 deficit against Sweden from the first-leg in order to qualify for the World Cup.But, if the second-leg turns out to be Buffon’s final match, he will be bowing in in style as you’d expect.While Buffon is one of the most-loved players in world football, it’s unfortunate that the Italian fans decide to often boo the national anthem of the opposition.But this is where Buffon often produces an incredible act.We’ve seen it happen before and, once again against Sweden, Buffon decided to applaud their anthem amidst all the boos.This time, though, the legendary ‘keeper looked rather emotional while he did - probably knowing that this could be the last time he represented his country.

Watch: Buffon's class act

Take a look:

Twitter reacts

And this is how Twitter reacted as they applauded him for applauding the national anthem of the visitors:

It was only a couple of weeks ago that the Juventus stopper confirmed that he’s hoping his last act as a footballer will be in Russia next summer. But after coming off second best against Spain in their group, they will have to do it the hard way via the playoffs.

Buffon on his future

But, unless he wins the Champions League with Juve, Buffon will be hanging up his gloves next summer whether he’s qualified for the World Cup or not.

"This is my last season and I am quite convinced of the choices I take," he told Sky Italia. "I am a very calm person, in the sense that I am not afraid of the future and of what my life may be.

"It would not change anything to play for one or two more years. It would take nothing or add anything to what I have already done. The only way would be to win the Champions League and, at that point, to try to win the Intercontinental. Maybe (Wojciech) Szczesny could play a game and me another.

"But I think with a goalkeeper like him, it is normal that next year I'll be aside."

We’ll certainly miss lovely moments like this - as well as his incredible saves - when Buffon does leave the game.
