Sky Sports Sources understand Wigan winger Charles N'Zogbia's proposed move to Birmingham has collapsed after the player failed to agree personal terms.
The Latics accepted an offer from the Blues for N'Zogbia on Friday after the Frenchman was strongly linked with a move away from the DW Stadium.
But recent reports suggest the deal has stalled after 24-year-old N'Zogbia was unable to reach an agreement with the Midlands club.
Birmingham saw an offer for N'Zogbia rejected by Wigan earlier this summer before manager Alex McLeish tabled a new bid this week.
Former Newcastle man N'Zogbia has also reportedly attracted the interest of Sunderland and French giants Marseille.
