Leeds manager David O'Leary has admitted he would have to "freshen things up" in the summer in his bid to win a first trophy as Elland Road boss.
With Leeds' season looking increasingly in danger of ending in failure after their slump in league form and elimination from both domestic cups and the UEFA Cup, O'Leary hopes to sign more new players.
O’Leary has spent around Stg£100 million since taking over from George Graham in October 1998, but he claims more investment is needed to take United to "another level".
O'Leary told BBC Radio: "Over the years I have known a lot of clubs to spend a lot of money and not get a lot back. I think we need changes here in the summer to freshen things up.
"It is not a case of selling the silverware, we will do what we think is right to improve the team in general.
"I always think a few new players freshens things up and makes people hungry again.
"I am going to try and get some new players here, without a doubt, players that will take us to another level."
