The Senegal international spent last season at Ewood Park on loan to Blackburn Rovers, but at the end of that spell the 23 year old returned to Old Trafford.
At the moment, with so many attacking options at Old Trafford, the youngster does not stand much of a chance of managing to get a league game, even though Ferguson highly rates him.
He has played in the Carlin Cup games, but Diouf knows that he needs more first team experience and him looking for a loan would alert many Championship sides.
Diouf told Sky Sports: "It is not easy for me, but to be honest unless you are Messi or Ronaldo you are not going to get in the attack of Manchester United.
"Sometimes you have a winner of the Golden Ball (Owen) or last season's top scorer (Berbatov) not even on the bench, in the last game the striker substitutes were: Rooney and Hernandez.
"I will keep on fighting and see, going on a loan to play regularly would benefit both parties."
