OXFORD United need to be flexible when structuring deals this summer, with boss Karl Robinson not expecting to have big money to spend on tranfers.

The close season has started slowly for the U’s, who were aiming to hit the ground running.

Cameron Norman is the only new signing they have got over the line, while fees have been agreed for Ryan Ledson and Kane Hemmings to leave.

United’s recruitment staff are working hard behind the scenes on a wide variety of targets.

While there is scope to pay fees, Robinson ruled out paying significant six-figure sums.

The United boss said: “If the price is right we’ll pay.

“We’re not going to be paying £400,000 or £500,000 for anybody, but I think we can do it on games played, promotion, percentage of sell-ons, whatever it may be. We can be creative.”

The key to the deals rest with U’s owner Sumrith Thanakarnjanasuth, who helped provide the funding which saw Rob Dickie and Cameron Brannagan sign from Reading and Liverpool respectively in January before officially taking charge of the club.

The businessman, known as Tiger, will consider each investment on a case-by-case basis.

“Tiger’s always saying ‘come to me, ask the question and I’ll give you an honest answer’,” Robinson said.

“If the right player comes along I don’t think the club has been averse to pushing the boundaries.

“I have an understanding of the realms in which I’m working, but if we feel it needs slightly nudging up then it’s an adjustable ceiling.

“But don’t take too many risks with it, don’t be disrespectful with somebody else’s money.

“A manager can leave a club in a tremendous meltdown if you’re overspending and get the wrong players in.

“It’s important we find the right ones to be competitive.”

Hemmings’s exit increased United’s need for added firepower up front this summer, while multiple wide players are also on the wish-list.

One winger who has become available is Mark Marshall, who Robinson signed for Charlton Athletic last summer.

The 31-year-old is free to leave, despite having 12 months left on his deal at the Valley.
