Did Christensen refuse to play FA Cup final?

Andreas Christensen's future seems to lie at Barcelona. The central defender has his days numbered at Chelsea and his immediate future lies at a Barcelona who are hoping to improve their defensive frailities with his arrival. 

However, he is still a Chelsea player for now. This contrasts with the attitude which he has allegedly adopted recently. At least, this is what 'The Telegraph' reports.,

According to the English media, Thomas Tuchel included the Dane in the starting XI for the FA Cup final against Liverpool. However, that same morning, the centre-back told the coach that he felt unwell to play. 

The German coach decided to play Antonio Rudiger and Thiago Silva. A situation which has caused anger at Stamford Bridge because some supporters think he refused to play.
