Towering Serbia striker Nikola Zigic looks all set to sign for Birmingham after undergoing a medical.
The 6 foot 8 inch Valencia forward has been on Blues boss Alex McLeish's radar for some time and it's understood he flew in for tests last night ahead of a deal worth in the region of €7 million between the clubs.
McLeish had been linked with several strikers in recent weeks including West Ham's Carlton Cole and Fulham's Bobby Zamora.
The Scot is maintaining his policy of not commenting on potential signings until any deal has been completed, although he confirmed bids have been put in for players.
Sources closes to Blues indicated earlier claimed the midlands club are "further down the line than anybody" in the race to sign the giant 29-year-old, who has been linked at various times with a host of Barclays Premier League clubs including Chelsea, Liverpool, Stoke, Blackburn, Sunderland, Aston Villa, Fulham, Everton and Tottenham.
McLeish would only say: "There are irons in the fire. We've been linked with one or two players, we have put in bids for players.
"It would be unfair of me to talk about names at the moment. It would be unfair to the clubs and also to the fans if things don't happen.
"But I think they will be excited about one or two of the names we are pursuing and what we are trying to add to the squad is players of quality."
Zigic has been tipped by Serbian coach Raddy Antic to be one of the stars of the forthcoming World Cup and he has netted 16 times in 42 internationals.
He initially made his name at Red Star Belgrade with 71 goals in 110 games before moving to Racing Santander.
A €17.5 million switch to Valencia three years ago has not been successful as Zigic would have hoped and he even returned to Santander for a loan spell at one stage.
Last season he scored nine goals in 28 games for Valencia but David Villa was often preferred as the lone striker before his move to Barcelona.
McLeish continues to be linked with Zamora, while he is understood to have had an €9.3 million bid for Wigan's Charles N'Zogbia rejected.
