The Chile striker has struggled to find his best form for Manchester United since his January move from Arsenal.
He has scored only three goals but one of them was the equaliser in the 2-1 semi-final win over Tottenham which made it eight goals in just six appearances at the national stadium.
Sanchez’s run started with a brace for Chile against England in November 2013.
The following season, his first with Arsenal, he scored twice in their FA cup semi-final win over Reading and netted the second in the 4-0 win over Aston Villa in the final.
Then, in 2016-17, he scored in the Gunners semi-final win over Manchester City before grabbing the first in their victory over Chelsea in the final.
