The duo could become the latest high-profile names to join Dean Saunders' squad, following Pascal Chimbonda, El-Hadji Diouf and Habib Beye to the Keepmoat Stadium as part of an ambitious transfer policy fronted by McKay.

A deal for West Brom striker Fortune is close to completion with Thursday's emergency loan deadline on the horizon.

According to McKay, Baggies boss Roy Hodgson will give the deal the all-clear if Shane Long suffers no reaction to his recent knee injury picked up in training.

McKay told Press Association Sport: "We're waiting for a player to come through training on Thursday, Shane Long, and if he's okay West Brom will allow Marco to come and join us. It would be until January 4."

Former Holland midfielder Zenden is also on Rovers' radar. He has been without a club since his release by Sunderland at the end of last season and recently failed to win a contract at Celtic, but his time in Glasgow brought him to the attention of Hoops fan McKay.

"We've spoken to Bolo," he added. "He played for Celtic in a friendly against St Johnstone. I'm a Celtic fan myself and I was told he was outstanding. But he couldn't agree anything there and we've been in contact with him."
