Willian says moving to Chelsea was always a career dream.
The midfielder has proved a great coup since his arrival from Shakhtar Donetsk.
He told chelseafc.com: "I knew Chelsea had made some offers while I was at Shakhtar so when I eventually arrived here, after a short spell with Anzhi Makhachkala, it was amazing. Having David Luiz, Oscar and Ramires here when I joined was very important for me because they helped me a lot with the language and inside the club, so it was very helpful.
"I told myself I had to start again because at Shakhtar I had my position and I always played. Everyone knew about my profile and how I played. I knew I had to start from zero to prove myself because it was a new club, new team-mates, new fans, and we had Jose Mourinho who was a big manager. He gave me a lot of confidence to show my quality."
