The Chile international completed his headline-grabbing transfer to the Old Trafford club last month after weeks of speculation linking him with a move away from The Emirates.
Sanchez ended up signing for Manchester United as part of the same deal which saw Henrikh Mkhitaryan head to Arsenal.
The 29-year-old opened his goal-scoring account for his new club last weekend when he scored from the penalty spot in his side’s 2-0 victory over Huddersfield Town.
Sanchez will be hoping to find the net for the Red Devils when Manchester United travel to Newcastle United in the Premier League on Sunday afternoon.
And the Chilean has now lifted the lid on his decision to sign for the Red Devils from Arsenal last month.
Speaking in an interview with Sky Sports, Sanchez said: “I came here to win [things]. I left Arsenal because I wanted to develop and learn as a 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.”
Manchester United are currently in second place in the Premier League table and 13 points behind leaders Manchester City as they look to try and get as close to their bitter local rivals in the table as possible.
The Red Devils will take on Spanish side Sevilla in the last 16 of the Champions League later this month.
