Forward Alexis Sanchez “does not regret” joining Manchester United but says he did not get enough playing time to be a success.
The Chilean, 30, joined Inter Milan on a season-long loan deal in August after 19 months at Old Trafford.
He was United’s highest earner on about £400,000 a week – but scored only five times in 45 games after joining from Arsenal in January 2018.
“I’m very happy I went to Manchester United,” Sanchez told BBC Sport.
“I’ve always said that. It’s the club that’s won the most in England.
“When I went to Arsenal it was fantastic – I was happy there – but United were growing at the time, they were buying players to win something.
“I wanted to join them and win everything. I don’t regret going there.”
“I think that I’m happy when I play for my national team,” he said.
“I was happy at Manchester United too, but I’ve always said to my friends: I want to play.
“If they would let me play I’ll do my best. Sometimes I’d play 60 minutes then I wouldn’t play the next game – and I didn’t know why.”
