The Chilean couldn't find any his form in his two-year spell at United, scoring only five goals in 45 matches.
Alexis Sanchez has revealed he wanted to leave Manchester United after having just one training session with the club.
The Chile superstar left Arsenal to join the Red Devils in January 2018 after four-and-a-half seasons at the Emirates.
Sanchez spent 18 months at Old Trafford before he was loaned out to Serie A club Inter Milan.
In a video posted on his Instagram page, Sanchez spoke about his experience at United.
"I remember the first training session I had, I realised a lot of things," he said. "After the session, I got home and I told my family and my agent ‘can you not rip up the contract to go back to Arsenal?’.
"They laughed, I told them there’s something that doesn’t sit right, it doesn’t seem good. But I already signed, I was already there.
"After the first few months I carried on having the same feeling, we weren’t united as a team in that moment."
The 31-year-old added: "I accepted the opportunity to go to United, it felt tempting and it was something good for me, I liked this club a lot when I was a kid. Eventually, I signed but I didn't ask for information on what was happening inside the club.
"Sometimes there are things that you don't realise until you get there, and I remember the first training session I had, I realised a lot of things."
