Barca pull off the mother of all comebacks

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.

The comeback made them the first Champions League team in history to overcome a four-goal deficit for a win in a knockout round as well.

That hope was then seemingly extinguished by Edinson Cavani, who scored for the visitors in the 62nd minute and the away goal left the hosts needing three more to edge ahead and qualify.

Roberto added, "They say the fans are one more player, but today they were 10 more".

But with the Nou Camp rocking with almost 100,000 fans, the dream edged closer when Lionel Messi converted a 50th-minute penalty to make it 4-3 on aggregate and 3-0 on the night.

He had called for a calm and measured approach before the match but he was anything but when the first whistle blew driving the home team forward.

Alexis Sanchez in Arsenal row
Craig Burley can not wrap his head around why Alexis Sanchez would sign a new deal as Arsenal are trending backwards. It's not always going up". "We have to look to close the gap on the top teams and aspire to be amongst the best".

PSG still know that two minutes into five minutes of stoppage time they are still the strong favourites to go through on away goals, but there was a sting in the tail.

Then with the 90 minutes nearly up, the second member in Barcelona's striking trio, Luis Suarez, earned a penalty amid suggestions he dived in the box. But if anyone's capable of such an extraordinary comeback, it's Barca at the Nou Camp. The French side was on the verge of avenging quarterfinal exits to Barcelona in 2013 and 2015 and earning an elusive marquee victory that its Qatari owners were longing for. If any went, stuff them, they have missed a historic night. A lot of things can happen in 95 minutes, and hopefully they will be positive. It was every bit as scrappy as the first with Iniesta back-heeling the ball from the byline into a crowded six-yard box and Layvin Kurzawa putting it past his own goalkeeper. First game was played in Paris. "Then in the last two minutes we lost everything we had recovered in the second-half".

"We changed to a 3-4-3 in a diamond formation so we could have more ball possession and more control the game", Luis Enrique said.

Neymar found the net with a brilliant curling free-kick before in the final minute of normal time the Brazil worldwide struck from the penalty spot after Luis Suarez was fouled.

Having Neymar, Messi and Luis Suarez in the Barca line-up is a good start.
