Alexis Sanchez moved to Old Trafford from Arsenal in January in a swap deal that saw Henrikh Mkhitaryan move the other rival side.
Chile international has described his new team as “the biggest club in England” and says he wants to win every trophy available to him while with the Red Devils.
The 29-year-old admits that he left Arsenal in order to “develop and learn as a player” and hopes to make the most of his time with his new club.
“I think that Manchester United, since I was young - and I’m not just saying this because I’m here, I’m an honest guy and I never lie - I think it’s the biggest club in England. That’s what I think,” Sanchez told Gunners legend Thierry Henry on Sky Sports.
“There are lots of big clubs, and having played for Arsenal, they are also one of them. It’s a huge club and I was there.
“But coming here, looking at the badge, I think United have to win everything because it’s such a big club. The club crest says it all.
“I came here to win. I left Arsenal because I wanted to develop and learn as player, and get to experience a new club.
“Manchester United are a huge club on the global stage. I came here to win everything. Otherwise I wouldn’t have come here.”
Alexis Sanchez left Arsenal under a cloud after running down his contract and fans were beginning to accuse him of ‘phoning it in’ as he eyed a January move elsewhere.
A deal to Manchester City looked on the cards until Arsenal got wind of United’s interest.
The former Barcelona forward scored 80 goals in 165 appearances for Arsenal and managed to open his United account earlier this month.
The Chile international scored his side’s second goal in a 2-0 win over Huddersfield, stabbing home the rebound from his own penalty which had been saved by Jonas Lossi.
