The Senegal forward joined Rovers on a season-long loan from United last month.
The 22-year-old has already made an impact at Ewood Park by hitting a hat-trick in a Carling Cup tie against Norwich and then scoring past Arsenal in the Premier League.
Diouf told the Lancashire Telegraph: "For me it's not about getting attention from United now. It's about working hard for the team I'm playing for.
"Now I'm playing for Blackburn so I have to give my best here.
"I will be focused on Blackburn now and we will see after."
