Paul Pogba has cast doubt over his future at Manchester United after revealing he is considering "a new challenge".
Speculation on a possible move to Real Madrid or a return to former club Juventus has been mounting since a season in which Pogba faced criticism at times for his performances with United.
The 26-year-old told reporters in Tokyo while attending an event held by sponsors Adidas that it could be time to leave Old Trafford.
"Like you said, there is a lot of talking and a lot of thinking as well," the France midfielder said.
"For me I have been for three years in Manchester and have been doing great; some good moments and some bad moments, like everybody. Like everywhere else.
"After everything that happened this season, with my season being my best season as well... I think for me it could be a good time to have a new challenge somewhere else.
"I am thinking of this: to have a new challenge somewhere else."
United boss Ole Gunnar Solskjaer has made clear he will start to rebuild his squad this summer, but the club is likely to only consider a huge offer for one of their prize assets.
Pogba was re-signed by United in the summer of 2016 from Juventus for a then world record transfer fee of £89million.
He had spent four years with the Italian club after being sold to them by United for £1.5m in 2012.
