The Blaugrana supremo was keen to heap praise on the man who led the club to 14 titles in four seasons, while at the same time expressing his faith in his successor
Pedro struck twice either side of a goal from Lionel Messi as the Blaugrana claimed their 14th trophy since the arrival of Guardiola as coach in the summer of 2008. As far as Rosell was concerned, it was a fitting finale for the former Barca midfielder.
"It was an end to honour the best coach in the history of the club," the Blaugrana supremo enthused. "Tito will continue the legacy."
Rosell also had some kind words for a distraught Athletic, who ended what was a wonderful campaign empty handed after losing their Europa League decider against Atletico Madrid by the same 3-0 scoreline.
"I must congratulate Athletic, a club that we all have to learn from," he claimed. "But today, Barcelona played better."
Guardiola announced in April that he would be standing down as Barca boss this summer and the 41-year-old is now set to take a year-long sabbatical from the game.
