England coach Trevor Bayliss says the speculation over Alastair Cook's future as captain is a "pain in the backside".
Before the series in India, Cook said he was looking forward to not being skipper and after the fourth Test defeat on Monday he admitted to having "questions" over his role.
"It's a little bit aggravating," Australian Bayliss said.
"I think everyone, to a man, in the room would be disappointed if he wasn't captain next year."
Cook, who will be 32 later in December, took over as captain from Andrew Strauss in 2012 and has led England in a record 58 Tests.
