Manchester City hero Tony Book is convinced they can win the Champions League this season.
Book is the only Manchester City captain in the club's history to lift a European trophy, the Cup-Winners' Cup of 1970.
He told the Daily Mail: "It's only a matter of time before Pep Guardiola delivers a European trophy.
"The two games against Liverpool are going to be tough but I'd say that City have the best squad and manager in Europe. They have more quality in depth than either Barcelona or Real Madrid, they can go anywhere and win.
"People still talk to me about being captain of a great City team, but I think Vincent is already on a higher level."
