Chelsea winger Willian says it was "very difficult" to work with former Blues boss Antonio Conte but admitted he has high expectations for new manager Maurizio Sarri.
The former Shakhtar Donetsk star had a rocky relationship with Conte during their two years together at Stamford Bridge, with the Brazil international at times finding it difficult to hide his disillusionment with the Italian coach.
Willian had seen his playing time significantly decrease at Chelsea after storming down the tunnel during an April FA Cup semifinal win against Southampton and he refused to discuss his relationship with Conte in an interview with ESPN Brasil the following month.
