The 20-year-old striker scored 15 goals as the Tigers secured promotion to the top flight during a successful loan spell from Manchester United last season and Brown is keen to open discussions with the champions after their upcoming tour of South Africa.

Brown said: "I spoke at length with Sir Alex Ferguson at the end of the season. When they come back from South Africa there is an opportunity to talk again. There is always a possibility."

Campbell is likely to command a fee of around £5million and other clubs, including Aston Villa, have also been linked with the youngster.

It is unclear whether United would sell but such a priority is he that Brown would also be interested in bringing the player back to the KC Stadium on another loan deal.

"He is very, very important to me, and that we get the right quality strikers in," Brown added.

"It is difficult. There are one or two strikers out there we have earmarked as priority but if Fraizer Campbell became available we would certainly be interested in taking him, either permanent or on loan."
