Leeds manager Simon Grayson will target experienced players in the transfer market this summer.
Grayson revealed he is already looking to strengthen his squad after seeing his side's 2-1 win at champions QPR leave them three points short of a play-off place.
When asked what was required, Grayson replied: "Probably a bit more experience. There have been times when we have shot ourselves in the foot.
"When we were 4-1 up against Preston at home and then lost 6-4. We also lost at Barnsley when we were sitting comfortably, but we have the nucleus of a good squad."
He added: "We have players who are hungry and who work hard for each other and they want to get better. I know what we need to get and hopefully we will manage to achieve that."
Grayson said he hoped the allure of playing for a "top-six" club would help attract better players to Elland Road.
"We have never found it difficult in the past because of the size of our club and the facilities. It is also a club which is moving forward. A big football club and our attendances are around 28,000 this year. In terms of size of our fanbase we're probably in the top six in the country," he added.
