Chelsea boss Andre Villas-Boas has hailed the mental toughness shown by John Obi Mikel in the wake of his father's kidnapping.
For the second week running, Mikel has volunteered to continue playing, despite the trauma of knowing Michael Obi is being held captive in his family's native Nigeria.
Mikel's representatives on Friday confirmed a "sizeable" ransom had been demanded for the release of the midfielder's father, who was abducted last week.
Villas-Boas broke the news of the kidnapping to Mikel on Saturday, 24 hours before Chelsea's opening game of the season at Stoke, but the player still insisted on playing at the Britannia Stadium.
Villas-Boas acknowledged the response of Mikel, who has also put his hand up for Saturday's clash with West Brom, had demonstrated "amazing mental toughness".
"I just have to go with the word my player gives to me and for the game against Stoke, Mikel felt well to play," noted Villas-Boas.
"People go through big disappointments and personal things in their lives and they can still be able to play because they feel well on the pitch, to avoid the things that are running in their personal lives and they can focus on different things.
"Mikel made himself available for training and selection so I will just judge it like that.
"Players react in different ways.
"Some players want straight away to go back to their families, others prefer to be like this and live on day by day, not because they think they are distanced from where it is happening, but it's their choice."
Villas-Boas admitted it had been "difficult" breaking the news to Mikel but would not be drawn on further discussions between the pair.
"I wouldn't like to go into it - it's a pretty sensitive situation and pretty traumatic," added Villas-Boas.
"Hopefully, he can get this thing solved as soon as possible that's what we hope for."
