Bemba Dieng has failed his medical at OGC Nice, you couldn't make it up

Marseille forward Bamba Dieng has failed his OGC Nice medical in the final hours of transfer deadline day.

So, let me bring you up to speed on the unfolding events.

On Thursday afternoon, it was reported that Premier League outfit Leeds had agreed a €10million deal for the services of highly-rated Senegalese international Bamba Dieng.

The 22-year-old was expected to travel to the UK and undergo a medical before signing a four-year deal at Elland Road.

In fact, Leeds owner Andrea Radrizzani tweeted at 1pm to confirm the club's intentions. "Let's welcome Bamba Dieng and we will continue to work on [Cody] Gapko," he wrote.

"Now it's time to focus on the pitch and support our new project and the great job Jesse and the staff are doing."

A few hours later and that deal was put into jeoprady when Ligue 1 side OGC Nice decided to make their interest known.

After sitting in an airport terminal with a private aircraft on standby for a large chunk of the afternoon, Dieng decided to snub Leeds and travel to Nice for a medical – a decision that infuriated Jesse Marsch's side.

Fast forward to the latter stages of Thursday's transfer window and in another dramatic turn of events, the Marseille forward failed his medical.

Nice-Matin journalist William Humberset confirmed the news at 10:05pm, saying: "The 22-year-old did not satisfy the Nice leaders during the medical visit."

Transfer expert Fabrizio Romano would label it "the most incredible story of the day" and well, it's hard to disagree.

Jesse Marsch wanted to strengthen his forward line on deadline day and it appears the West Yorkshire-based club managed to swoop Willy Gnonto from FC Zurich at the last minute.

Dieng, who scored 7 goals in Ligue 1 last season for Marseille, made his feelings known about a move, while a deal to sign PSV's highly-rated forward Cody Gakpo also collapsed.

Dan James, meanwhile, has joined newly promoted Fulham after he completed a medical on Thursday.
