West Ham manager Alan Curbishley has not given up hope of landing Birmingham defender Matthew Upson.
The Hammers have had two bids for the defender batted back by Birmingham who confirmed a second offer of £6million had been snubbed on Tuesday.
Curbishley can understand Birmingham's position, with Blues eager to keep Upson in their promotion-chasing squad, but the West Ham chief hinted another bid could be lodged before the transfer window slams shut.
"It is difficult," said Curbishley.
"Steve Bruce was not happy with getting an enquiry for one of his players when they are sitting near the top of the league - but I have no idea why it has been publicised.
"We certainly were not responsible for it.
"We will just have to wait and see what happens with Matthew Upson. It is not clear yet."
Curbishley is also looking forward to completing the deal for Sevilla forward Kepa Blanco, with The Hammers close to sealing his signature.
"No medicals have been done yet but I would be delighted if he joined," he added. "He is a different sort of player to what we already have. He is good in the air and aggressive.
"A few clubs were chasing him and I am sure he will do well for us if he comes."
