The 48-year-old regards the present Blaugrana squad as the greatest of all-time, and has insisted that they are always looking to sign the best players
The Primera Division leaders have been one of Europe's dominant forces in recent years, and Rosell feels that they are even better than the Ajax and Bayern Munich teams from the 1970s and Arrigo Sacchi's AC Milan.
"This Barcelona are the best team ever. They say that everything moves in three-year cycles. We've already had four great years, though. We'll see how the fifth one turns out, but it's looking good," Rosell told Sic Noticias.
"This team has already broken the three-year rule. There will eventually be a dip, but the club's objective will be to ensure that it’s short-lived and isn't too major."
The Barca supremo then went on to discuss the potential arrival of Santos sensation Neymar, and insisted that the Blaugrana always try to sign the best players.
"Barca always wants the best. In addition to those brought up inside the club, we're always looking for players who can improve the squad. I don't know in Neymar's case, though. He's a Santos player until 2014."
