According to Xavi, who could make his 150th champions league appearance today, Guardiola perfected Barcelona.
Guardiola who is now at the helm of Bayern Munich, oversaw Barcelona for four years, in which he won 14 trophies for the Catalan club.
“Pep is fantastic and perfected the game of Barcelona .He revolutionised football and now we have him as a rival. It is a strange feeling to see him on another bench,” the veteran told Adidas Gamedayplus.
“We know him and he knows us. We know how he works. He will want to take possession as he knows how much we suffer without the ball, and it will be a very attractive game.”
