We are very happy to have him with us. I can’t add anything to his career at Chelsea as a player.”But, over his first week in training, I’ve seen the way he wants to play, the way he wants us to feel the shirt, the way he wants us to train every day, it is something special.”Azpilicueta expanded on his plaudits, adding that Lampard’s commitment to Chelsea during his playing career sets the perfect example for the current players to follow.”He was here for a very long and very successful period, and always set an example: how he wanted to break every record or improve himself in every session,” Azpilicueta said.”We have to be grateful and feel the passion for the shirt. We are very excited and the only way we can carry it on is by winning together, getting the feeling back of being all together as a club.”We have to take responsibility and know that there are a lot of things [going on] around us, but we have to work hard to get better.”Lampard’s first competitive game will be against Manchester United on the opening weekend of the Premier League season, before Chelsea face Champions League winners Liverpool in the UEFA Super Cup on August 14.
