Chelsea FC winger Florent Malouda said his team were just not efficient enough as FC Internazionale Milano pipped them to the UEFA Champions League quarter-finals, Samuel Eto'o's goal at Stamford Bridge sending them through 3-1 on aggregate. "The team that made the first mistake were going to be punished," Malouda said. "Samuel Eto'o was efficient. We had changes but the most efficient team advanced. We're disappointed but there are lots of other games left this season."
