Javier Hernandez has always enjoyed a good goalscoring record against Chelsea since joining United in 2010.
The Mexican marksman has managed seven goals in eight starts, with a three further appearances as substitute, versus the Blues - more than against any other club.
After netting on his debut in the Community Shield at Wembley, he has remained a constant thorn in the Londoners' side and has scored in three different competitions against them this term.
With Sir Alex always mindful of how his players perform against certain opposition, Hernandez will hope to be involved in Sunday's clash at Old Trafford.
