Why Folarin Balogun's Everton move collapsed on Deadline Day leaving Toffees, Chelsea and Monaco frustrated

The biggest controversy of the summer transfer window happened on Deadline Day, involving three clubs and two players.

The two Premier League sides were particularly left fuming about the situation.

Monaco needed to make a sale to help resolve a debt issue, while Everton needed a striker.

Balogun became a solution for both parties, and a £40m agreement was reached - but then came the first issue with the deal.

There was a problem with the USA international's medical after Everton found evidence of an injury, which Monaco and the player refuted, claiming he was fit to play immediately.

With the 11pm deadline approaching, Everton decided to proceed with the transfer but attempted to renegotiate the deal on cheaper terms in case the injury left him unable to play.

The club-to-club deal became much more performance-related, with clauses inserted that meant Monaco would get less money if Balogun could not play.

Crucially, it is understood nothing changed with Balogun's personal terms.

Amid a renegotiation of the Balogun deal, Chelsea reached an agreement with Monaco to sign midfielder Camara as a replacement for Fernandez, who was set to join Manchester City in a joint-British record £125m deal.
