To return to greatness, the Blaugrana squad needs to sign players who share the same philosophy as the club.
Barcelona could only lift one trophy this past season, after winning the Spanish La Liga tournament.
The team failed to qualify to the UEFA Champions League Final and lost the Copa del Rey against Valencia.
Which is why Deco believes the Blaugrana need better signings for the upcoming season.
“I like him [Frenkie de Jong],” Deco told Sport.
“He’s a great, young player and Barça, of course, need more players if they are to win the Champions League.”
“They are dominating LaLiga but yeah, he’s a signing for the future,” he added.
“I have a lot of respect for the Premier League because, for me, it’s the best league in the world.”
“But I also believe the best two, no three, clubs in the world are Barça, Real Madrid, and Manchester United,” he said.
“In that sense, there’s no comparison between playing for Barça or in the Premier League.”
What would Deco change to boost Barcelona to Champions League glory: “I don’t know. It’s difficult to answer that because Barcça has already won so much.”
“They’ve won LaLiga, reached the semi-finals of the Champions League, some quarterfinals too. They’ve been close to the final but they all need to improve.”
