Barcelona boss Frank Rijkaard insisted that his side were ready for their UEFA Champions League round of 16 rematch against Premiership top club Chelsea that will take place at Stamford Bridge on February 21. "I feel no pressure before meeting Chelsea again," Rijkaard told French magazine L'Equipe on Saturday. "We know we have to be ready and not to make the same mistakes again,” he added. The Spanish champions suffered a 5-4 aggregate defeat to Chelsea in last season's UEFA Champions League round-two. The 44-year-old caretaker also indicated that the team learned their lesson for last season's defeat and have dealt with their mistakes, and insisted that they were confident of winning the first-leg and qualifying to the quarter-finals. "At Stamford Bridge, we could not interpret their game and, above all when we lost the ball, we were too vulnerable. "Winning the Champions League after La Liga, that would be nice. But we won't succeed without working very hard," Rijkaard said. Barcelona will host the second-leg that will take place on March seventh.
