Meanwhile, Barcelona were knocked out by Roma in the quarter-finals, and Puyol is fuming that their rivals have excelled in the competition.
"I am convinced that we have a better team than Madrid, but they have won four of the last five Champions Leagues," Puyol told La Vanguardia.
"I think the solution comes from getting our priorities straight. We're losing an opportunity and I'm furious about that as a Barca fan. Winning the treble is extremely hard as statistics shows, so I think the most sensible thing would be to relegate the Copa del Rey. Don't get me wrong, I loved playing in the final, but the path there should be for the reserves and the young players to show if they are good enough or not.
"We have a great team and we have Leo [Messi], I think the Champions League has a much bigger global impact and also [impacts] on the Ballon d'Or. I have no doubt who is the best player in the world but Messi should be showing his talent above all in La Liga and in Europe, I'm sure he'd agree with me."
