While Neymar and Sergi Roberto were hailed as heroes following Barcelona's dramatic comeback against Paris Saint-Germain on Wednesday, one other player deserved huge praise.It was Barca's six goals that fired them through to the Champions League quarter-finals, of course, but goalkeeper Marc-Andre ter Stegen kept them in the game.In the 64th minute, shortly after Edinson Cavani scored PSG's away goal, Ter Stegen produced a wonderful save to deny the Uruguayan in a one-on-one situation.Indeed, had Cavani scored, the game would have most definitely been over.But Ter Stegen's influence didn't stop there. The German, having pushed up in the final few minutes in search of a winning goal, picked up possession in PSG's half and was fouled by Marco Verratti.And we all know what happened next. Neymar took the resulting free-kick and found Roberto, who poked past Kevin Trapp to score a 95th-minute winner.What a moment - and it all stemmed from the 24-year-old goalkeeper.In the days since the historic win, various stories have emerged of what certain players said on the pitch during the game.PSG's Verratti, for example, revealed yesterday that some of Barcelona's players told him the game was finished when Cavani scored just after the hour mark.And according to Neymar, he told Roberto where he was going to cross the ball moments before actually taking his free-kick. A fresh revelation has now been made by Javier Mascherano, who claims Ter Stegen shouted something brilliant at Barcelona's players after Cavani struck.The Argentine said on Thursday: "After we conceded the goal, Ter Stegen started screaming: 'We never die, we are Barcelona!'

"He continued screaming: 'We will win. We will win!' At one point I told Busquets that Ter Stegen wasn't okay."

Wow, how's that motivation? Ter Stegen has really come into his own at Barcelona and he demonstrated his leadership skills at the Camp Nou by rallying his teammates.

Luis Enrique's men looked down and out when Cavani scored but sheer determination meant they were able to pull off the greatest comeback in Champions League history.

Speaking after the game, Enrique described the game as one no Barcelona fan will ever forget.

He said: "This is a sport for mad people. Clearly for crazy people. Those who were at the Camp Nou tonight will remember it for the rest of their lives."
