Lionel Messi  says he feels honoured to be wearing the No.10 jersey at Barcelona  and follow in the footsteps of Ronaldinho  and other club legends.The Argentina international inherited Ronaldinho's number when the Brazilian left Barca for AC Milan in the summer of 2008 and he has claimed it marked a special moment in his early career."When they gave me the No.10 jersey, I was very proud and happy to wear it. It's the shirt that has been worn by some impressive players at the club," the Argentine reveals in an advert for Audemars Piguet."Ronaldinho had worn it and he did a great many things for the club. It was a fantastic responsibility for me to have the No.10 shirt that he had worn and which had been worn by many others."The prolific attacker then went on to voice his ambition to guide Argentina to World Cup glory, while he also wants more silverware with Barca."I dream of being a world champion, of winning things with Argentina," Messi added."And I dream of being able to win the the titles that I have already won with Barcelona again in the future."Messi guided Barca to the Liga title this term with 46 goals in 32 league appearances.
