The Sheffield United manager wants the former Real Madrid and Everton man to marshall his midfield as he prepares for life in the Championship.

With the Blades' relegation triggering a £4 million release clause in Phil Jagielka's contract, Robson needs a new midfield general.

"I have an interest in Thomas Gravesen and would like to bring him to Sheffield United," said Robson.

"We are in discussions with Celtic over the issue and, hopefully, we can sort out some kind of agreement with them.

"I'm not sure if I can persuade Thomas to come here but I'd like to have the chance to speak to him."
