Eden Hazard admits joining Chelsea is a dream come true.
And he insisted he is ready to prove Roman Abramovich was right to make him the second most expensive signing in Chelsea's history.
He stated: "I am ready for the challenge and I know I will have to earn my place.
"That will come through training and pre-season at the start.
"After that, I know football goes very quickly. You can play a good game and earn your place.
"But the opposite can also happen. You must concentrate 100 per cent all the time and in every training session.
"The French like to watch the Premier League and even I did, too. I think it's the biggest and most beautiful league. The whole world watches it and I will need to be on top of my game and play good matches.
"Now I have a month of holiday. I will take advantage of it and will be raring to go in pre-season."
