The Nerazzurri supremo feels the Catalans are tedious to watch, while he has also explained their decision not to sign Paul Pogba this summer
The Catalan powerhouse have been one of the dominant sides in football in recent years, but Moratti struggles to appreciate their possession-based style of play.
"Football remains one of the mysteries of life and you never know how it will end. That's why I feel watching Barcelona is quite boring," Moratti told La Stampa.
"They would be even more boring to watch without Lionel Messi.
"I prefer quicker and a more direct style of football. A counter-attack, three touches of the ball and then a shot on goal."
The oil tycoon then went on to explain why Inter eventually opted not to make a move for Juventus midfielder Paul Pogba, who joined the Bianconeri from Manchester United in the summer transfer window.
"We followed him [Pogba], too. He seemed like a good player to me. We had an agreement with Manchester United not to approach each others players who were nearing the end of their contracts, though.
"It was a request from [Sir Alex] Ferguson, so we didn't go after him. Perhaps we made the wrong decision, but you can't snap up every player."
Pogba has impressed for Juventus in the opening months of the 2012-13 campaign, and helped the Turin giants to three points against Bologna in midweek by netting the winner well into stoppage time.
