Kevin Pietersen (left) seeks advice from Andy Flower
England denied a request from batsman Kevin Pietersen to make a brief return home during the West Indies tour.
Pietersen asked to go home for 48 hours midway between the third and fourth Tests because he was homesick, but the request was refused by management.
He said last week he was "at the end of his tether" with two more one-dayers still to play on the tour.
But stand-in coach Andy Flower has reaffirmed Pietersen's commitment to England's cause in the West Indies.
"Kevin is very proud about what he does and he's very proud of this team," Flower told BBC 5 Live's Sportsweek.
"He's doing everything in his power to win. He's been training as hard as anyone I can assure you, and he is very fired-up to win this one-day series."
Pietersen, 28, quit as England captain in January after a rift with coach Peter Moores, who was sacked.
In a newspaper interview he admitted to mental fatigue on the long tour, which comes to a close with the fifth and final one-dayer on Friday, 3 April.
"It's been a heck of a tough time and I'm at the end of my tether now," he told the Daily Mail.
"Really and truly I can't wait to get home."
But Flower insisted that any fatigue was associated with Pietersen's personal life and not his cricket.
"He didn't say he didn't want to play. What he meant, I believe, is that he wants to get home and see his family," said Flower.
"Sometimes in his downtime he gets a bit homesick like everyone, but this isn't a bad place to be - we all appreciate how lucky we are as international cricketers and he's no different in that regard.
"He appreciates where he is but, look, he's a little frustrated, he's said something in the press and that's been seized upon.
"The important thing is that these guys are playing for England. Everyone has to embrace that responsibility and enjoy it and in the main, that's the case."
