Eden Hazard has vowed to help Chelsea improve on the greatest season in their history after finally completing his move to the European champions.
Belgium star Hazard was confirmed as the Blues' second summer signing on Monday, almost a week after announcing he had decided to join them from Lille.
The Blues also won the FA Cup but finished only sixth in the Barclays Premier League and Hazard told their official website, www.chelseafc.com: "Chelsea had a great season, even if we didn't do very well in the league. By anybody's standards, winning two cups is a great achievement, so it will be a big challenge to do better."
