Sources at Chelsea expressed frustration and anger after the transfer deadline passed.
The club believed its move for Lamine Camara was effectively complete after agreeing a fee with Monaco, conducting a medical and reaching agreement on personal terms.
However, Chelsea say they were informed in writing by Monaco that the deal would not proceed.
No explanation has been given, although sources with knowledge of the situation believe the development may be linked to Everton's proposed move for United States international striker Balogun.
Everton maintained throughout deadline day that talks were ongoing despite reports casting doubt over Balogun's medical.
While some reports suggested the deal was off, Chelsea made progress in negotiations for Camara having previously struggled to reach an agreement with Monaco.
Sources in France had stated Monaco needed to make a major sale this summer and preferred to sell Balogun. A source at the Ligue 1 club had previously indicated it would take a "substantial fee" to secure Camara's departure.
Camara featured in Monaco's 2-0 win over Marseille on Sunday evening, while Balogun was left out of the squad.
Yet, when doubts emerged over Balogun's proposed move, Monaco's asking price for Camara appeared to fall, making a move to Chelsea more achievable at £47m.
Once Balogun's transfer appeared to be back on track, Monaco seemed more willing to generate funds through the striker's departure than by selling Camara.
As a result, Chelsea's hopes of ending the transfer window with a late signing were left frustrated.
Monaco have been contacted for comments but not yet responded.
