Birmingham manager Alex McLeish admits there is still a possibility of Nikola Zigic moving to Racing Santander while he hopes Obafemi Martins' arrival will come soon.
Spanish outfit Santander are known to be interested in tall striker Zigic and want to secure a deal before the end of the January transfer window.
An exit for the 30-year-old Serbian ace looked on the cards but McLeish admitted he could stay following an impressive performance in the Carling Cup against West Ham in midweek.
However, Santander are keen to land their man and the Blues boss says there may be movements before close of play on Monday.
"Santander have been in touch but we'll be together in the decision with the board as we always are," said the Scot.
"I said after the midweek game that it would be difficult to let Ziggy go on that kind of form."
On the prospect of landing former Newcastle forward Martins, McLeish added: "We're trying to get him. We're working hard on that but it's not a done deal yet."
Birmingham managed yet another superb comeback as they came from two goals down to advance to the FA Cup fifth round following a 3-2 win over Coventry.
The Sky Blues had taken the lead through Marlon King and Richard Wood but goals from David Bentley, Stuart Parnaby and Kevin Phillips completed a memorable turnaround.
On the game, McLeish remarked: "I wouldn't want to live through that too often with the stress levels but I thought the team played well today. There was a lot of really good stuff.
"We shouldn't have made it hard for ourselves because we started great. Coventry are obviously very dangerous up front.
"The big lad (Clive) Platt was a handful and of course we all know about Marlon King. But I knew there were goals in it for us.
"Bentley's was a cracker. We needed that. It was a turning point. If we'd gone in 2-0 down it would have been much tougher.
"The second half was again a measure of this squad's resilience and their desire not to give up until the final whistle."
Meanwhile, opposition manager Aidy Boothroyd was disappointed with his side's second-half showing.
He said: "I thought it was a terrific occasion and I'm afraid we got caught up in it in the second half and wanted to try to score three and four goals rather than being sensible.
"If somebody's bigger than you and better than you, you don't go toe to toe with them - and that's what we did.
"For some strange reason, despite what was said at half-time, we went all out to try to beat Birmingham City, a Premier League team, convincingly when really what we should have done was weathered the storm, kept calm and hit them on a sensible counter-attack."
