Almost everyone has written off the hopes of Barcelona getting back into the Champions League after suffering a 4-0 loss against Paris St Germain in the last 16 of the competition. No team in the history of European football has been able to overturn a 4-0 deficit from the first leg.

Former Barcelona defender Dani Alves, though, thinks that if there is any team that can achieve this feat, it may very well be the Catalan club. The Brazilian defender is widely known for his long spell with the Catalan club. He moved to the Camp Nou in the summer of 2008 for a figure of £ 25 million.

After managing to win every major honours including the Champions League and the FIFA Club World Cup on several occasions, Alves decided to bring his time with the Spanish club to an end. He was a surprise transfer to Juventus after letting his contract with Barcelona come to an end.

Alves is better equipped to talk about Barcelona than most of the pundits or former players. He says that the club are such a force going for that a potential comeback should not be ruled out under any instance. Barcelona have not gone out of the Champions League in the last 16 stage since 2007, such is the incredible dominance that they have had in this tournament.

"It's very tough to come back, not because Barca can't but because of the quality of their opponents. They press, they don't let you play. I always want them to do as well as possible. In football, anything can happen. If anyone can produce a comeback, it's the Barca machines,” said Alves after learning about the catastrophe suffered by his former team. Barcelona have not been recognisable to the monstrous juggernaut that won numerous trophies. Manager Luis Enrique has come under pressure this season.
