Goodwillie spent a second consecutive day in Blackburn today where he is believed to have undergone a medical after Rovers agreed a fee with the Clydesdale Bank Premier League club on Friday.

Rangers have had numerous bids rejected and were still submitting offers today, but they have not secured permission to speak to the player.

Blackburn's offer is reported to be £2million up front with a possible £800,000 more to come depending on future performance targets, with a sell-on clause also included.

Rangers, who initially bid around £1million, were hopeful today that their latest offer would convince United to allow Goodwillie to speak to them.

Rangers manager Ally McCoist revealed this morning his club was still in negotiations with United and he remained optimistic of landing the 22-year-old, who was today called up to the Scotland squad for next Wednesday's friendly against Denmark.

McCoist, speaking in Sweden ahead of the Champions League qualifier against Malmo, later confirmed a new bid had been submitted.

Asked if Rangers' latest offer was equal to that on the table from the Barclays Premier League club, McCoist said: "As far as I'm aware, yes.

"We believe that we have put a bid in that's more than acceptable."

However, the structure of the payments is reported to have been a stumbling block and time is running out for Rangers.

Blackburn will not comment on the situation until a deal is signed but that is expected to happen tomorrow unless Rangers can step up their efforts further.
