Chelsea boss Thomas Tuchel says Andreas Christensen's late withdrawal from the squad before the FA Cup final is "not the first time" the defender has felt unable to play this season.
BBC Sport understands Christensen, who was not injured, was due to play against Liverpool in last Saturday's Wembley showcase.
Speaking on Wednesday, Tuchel said the Denmark centre-half told him on the day of the final he was not ready to play.
"He had his reasons," added the German.
"They stay private and confidential."
Tuchel added: "But it was not the first time as you can see over the last weeks we had some of the same situations why he did not play so regularly.
