The Red Devils, in second place with 56 points, went scoreless in the first half at Old Trafford against a team buried in the 19th spot and struggling to avoid relegation, reports Efe.
Looking to give his team an offensive spark, United head coach Jose Mourinho sent out Paul Pogba and Marcus Rashford after the intermission, and shortly afterward Belgian striker Romelu Lukaku gave the home side the lead in the 55th minute.
Thirteen minutes later, Sanchez doubled that advantage by tallying his first goal in a United uniform.
The Chilean former Arsenal and FC Barcelona star, who had been awarded a penalty try, missed out on his initial chance from the 12-yard mark but put the deflected ball home.
Sanchez joined United from Arsenal during the winter transfer window in a swap deal that saw Henrikh Mkhitaryan move to the Gunners.
The Chilean had gone scoreless in a 4-0 win over Yeovil Town in FA Cup action on Jan. 26 and in United's 2-0 loss to Tottenham in a Premier League match on Wednesday.
