PSG players confronted by angry fans at airport - club

Kaka has some bizarre advice for Neymar

Cavani's goal made the tie looked to be over for Barcelona, but as they say, it isn't over till it's over.

It was the most extraordinary game I've ever had the privilege of watching and there can be no doubt that Barcelona's character - tremendous fighting spirit, pride in the team's colours and stoic refusal to be beaten - fully deserved the outcome.

After Barca could only sneak past Leganes in their first game after the nightmare in Paris, Luis Enrique rejigged his formation from 4-3-3 to 3-4-3, employing Sergi Roberto as an extra midfielder when the team had the ball.

The French defense was again at fault when Thomas Meunier lacked the pace to keep up with Neymar as he sped past him and into the area in an attempt to reach a well-placed through ball from Iniesta.

It could have been so different, though.

Edinson Cavani has scored seven goals in as many games in the Champions League this season, his best tally in the competition. It was the first goal Enrique's side had conceded at home in Europe this season, and how costly it looked. With the aggregate at 5-3 and a PSG away goal, Barcelona needed three goals to move on.

Barcelona have won 7-0 against Celtic, 4-0 against Manchester City and Borussia Monchengladbach at Camp Nou in the Champions League this season - three results that give them confidence they can cause the upset. Throw in Wednesday's 6-1 win over Unai Emery's side and Barca's aggregate score increases to 21-1 at home.

And what about Luis Enrique?

He had played his part with the third goal of the night, but the win owed as much to Luis Suarez's insatiable belief in the impossible, Neymar's jaw-dropping genius and the never-say-die attitude of a team who used to woo the world with its football but will now be remembered for its guts too. The last to do so was Barcelona's bitter rivals Real Madrid more than 30 years ago.

While they will need to score five or more goals to win the tie in regulation time or four to force extra time, a PSG goal would most certainly mean lights out for the Catalan club as they would need to score six to outright win the tie. This was about them all.

Enter Neymar, who lined up a free kick from the left side just outside the box. That time when PSG could only muster four passes.

Coming back from 4-0 down was going to pale in comparison to scoring three goals in the last seven minutes. When they arrived back in France, dozens of cursing fans waited in the pre-dawn dark.
