Wigan striker Hugo Rodallega will play against Tottenham on Tuesday night but could then sign for the London club straight after the match at White Hart Lane.
It is widely reported that Spurs are ready to rush through a deal to sign Colombia international Rodallega, who is out of contract at the end of the season and is refusing to sign new Wigan terms, before Tuesday night's transfer deadline.
And Wigan chairman Dave Whelan has told ESPNsoccernet he would not be surprised if Tottenham manager Harry Redknapp makes a late move for the want-away forward.
"We are used to Tottenham making a last minute bid on transfer deadline day, and by last minute, I mean the very last minute," Whelan told ESPNsoccernet.
"I have seen Spurs linked with Rodallega for some time, but we have not received a bid, not even an enquiry as far as I know.
"But that doesn't mean they won't make a bid, but if they do they always leave it late, very late."
Whelan added: "It might make sense to cash in now, but if he stays with us to the end of the season he can help us stay up, which would be worth far more than a transfer fee."
Spurs' game against Wigan is due to end just 90 minutes before the window shuts, but Spurs assistant coach Joe Jordan believes that the match against the Latics does not mean a last-gasp venture into the market can be ruled out.
"I don't think the game will affect things, really," he said. "There are people within the club that know what the thoughts of the manager are and they get on and do it.
"You concentrate on what job you are supposed to do so that's got nothing to do with it.
"Nothing is imminent as far as I am aware, but in the past Tottenham have come in with a late purchase and there's always a possibility in football."
Spurs have become infamous for their last-minute purchases on deadline day and have been linked with a host of players, including Rodallega and Blackburn pair Christopher Samba and Junior Hoilett, but their only capture so far has been the permanent signing of Juventus loanee Yago Falque.
Whether Spurs sign anyone before the deadline could depend on the movement of players out of White Hart Lane.
The likes of Giovani Dos Santos, Heurelho Gomes, Roman Pavlyuchenko and Vedran Corluka head a list of up to eight players who are either unsettled or want to leave the club after becoming frustrated at a lack of first-team football.
Sebastien Bassong has also been strongly linked with a move away from the club, although his departure will only come if Spurs snap up Samba as a replacement as they are already suffering from injuries at the back.
