Chief executive David Gill has revealed Manchester United haven't finished their summer spending spree despite splashing out £50million on three new players.
United boss Sir Alex Ferguson has already bolstered his title-winning squad with the captures of England midfielder Owen Hargreaves plus Portugal-based duo Anderson and Nani since the end of last season.
But Gill has revealed the Red Devils are still on the lookout for another striker to add to their contingent.
United have been linked with possible moves for Tottenham's Dimitar Berbatov, Barcelona forward Samuel Eto'o and Fernando Torres of Atletico Madrid.
"We have looked at it and we don't rule out another signing," said Gill.
"That area is a striker but we will see what happens. We're not desperate for it but if one came along that Alex felt would improve the squad we're prepared to do that."
Meanwhile, Gill has hinted there could also been some departures from Old Trafford during the close season.
He added: "There will be some changes but it would be wrong to comment as to that - but I think they are discussions we will have internally.
"We have a got a large squad now, so there should be some people leaving - not many at all.
"There should be some leaving and don't forget we have some great players coming back who have been on loan.
"We want competition for places, we are looking to improve the squad and to take it on from last year
"We are not resting on our laurels, we want to do even better next year on the pitch. Alex is always looking to improve the quality of the team we have out there."
