"I still have images in my head of when the game finished in London and we were out. I do not want this to happen again this year," Sky Sports network quoted Ronaldinho as saying on Monday.

Barcelona were knocked out of last year's UCL round of the 16 after losing 5-4 on aggregate against Chelsea.

The Catalans are looking to make up for last year's defeat when they visit the 'Blues' in the first leg of the UCL round of the16 on Wednesday.

Meanwhile, Barca's Portuguese midfielder Deco said that Chelsea boss Jose Mourinho is the main factor behind his side's success.

"I think that the best player at Chelsea is Mourinho, because he knows them all so well and makes his team fight to the very end," Deco told Barcelona's official website.

"The mentality of the team is the mentality of the manager. Mourinho has given Chelsea and his players the ability to win games and trophies that they did have before he took over.

"Every team has something of their coach's personality and Chelsea have Mourinho's mentality, a winning mentality, of working very hard and fighting for everything," the former Porto man added.
