Chelsea midfielder Willian has hailed the impact manager Jose Mourinho has had on his tactical evolution as a player and insists he fully adapted to the Premier League in his second season in England.

The Brazil international joined the Blues from Russian outfit Anzhi Makhachkala for £32million in the summer of 2013 and, after an unassuming first campaign played a pivotal role in Chelsea's title-winning season.

And the 26-year-old has paid tribute to his Portuguese manager for playing a key role in his development.

'Mourinho has been fundamental in my tactical evolution. This season I totally adapted to English football and succeeded in demonstrating evolution on the tactical side,' Willian was quoted as saying by Bleacher Report.

'I have looked to learn from each coach I work with ever since the youth ranks at Corinthians,' explains Willian. 'Lucescu [coach of Shakhtar Donetsk] was very important for my start in European football, I learned how to position myself differently on the pitch, how to defend more.

'The success of our team this season has a lot to do with the work that we initiated in the previous season. The club maintained the core of the team and brought reinforcements with some great players.'

Chelsea won the Premier League and the League cup this season but suffered a disappointing European campaign.

'It was really the low point of this season,' admits Willian. 'We encountered a great opponent with excellent players. Next season we will be stronger in the Champions League. Chelsea enters every competition with the objective of winning the title.'
