The Mexican striker joined United in the summer and has become an instant hit at Old Trafford.
Sanchez declard: “You just have to look at the team he’s signed for. It’s not just anybody who earns a transfer to Manchester United at that age.
“I think he’s in the most favourable environment possible but watch out, he shouldn’t be compared to anybody because that’ll burden him with unnecessary responsibilities.
“Since we [Mexico] have not got many players with exceptional talent, we’ve got to look after them.”
