London: Chelsea's last season's Footballer of the Year, Brazilian playmaker Willian has signed a new contract that will keep him at the English Premier League club until 2020. "I'm very happy to sign a new contract with Chelsea. It's a dream to continue with this club and over the next four years I will try to help the team win more trophies," said the player on Tuesday. "It's been an amazing time for me since I joined the club three years ago, I've won titles and last season I was named Chelsea Player of the Year. I hope to be able to stay at that level during the coming seasons and achieve more success," he continued. The Brazilian international, who scored six goals in 30 matches last season and who still had two years of contract with the Blues, arrived in London in August 2013 from Anzhi Makhachkala for 30 million pounds sterling ($39.7 million), reports Efe.
