It was supposed to be a special night for Gianluigi Buffon.
The legendary goalkeeper was making his 170th cap for Italy, making him the most-capped European player in international history.
And it was a huge match in which to reach the milestone - a World Cup qualifier against Spain at the Bernabeu.
The two nations went into the match level on points as they attempt to qualify for the Russian World Cup next summer.
But it wasn’t to be Buffon’s night.
In fact, the 39-year-old didn’t exactly cover himself in glory in Madrid.
Spain took the lead in the 14th-minute when Real’s Isco curled the ball over the wall and into the back of the net.

However, after looking at the replays, it appeared that the Juventus goalkeeper was at fault. Isco’s free-kick wasn’t near the corner and Buffon’s positioning must be questioned.
Well, that’s certainly the view of many football fans on Twitter anyway.
In fact, there were loads of people calling on him to retire from football.

Have some respect, guys.
While he may have been fault for the opener, there was nothing Buffon could do about Isco’s second goal.
The midfielder found space and drilled an effort with his left foot that clipped the inside of the post to double his tally and Spain’s lead.

Buffon on his future
While many were calling for him to retire immediately, Buffon is convinced that he will do so after next summer’s World Cup.
"I'm 99.9 percent certain of retirement," he told Sky Sport 24.
"I'm going to have one final, intense season, rich in big moments, and then it will be time to say enough is enough."
However, after this defeat to Spain, Italy face a tough task to actually reach the competition. It now looks as though they may have to enter the playoffs - a two-legged tie against another nation that also finished second in their group.
Let’s hope Buffon gets his wish and can play in one final World Cup, though.
