Nottingham Forest’s pursuit of Sporting CP defender Ousmane Diomande has collapsed, leaving fans in uproar after weeks of speculation. The 22-year-old Ivory Coast international was a top target for Oliver Glasner, but a valuation dispute-with Sporting demanding €40million (£34.3m)-has derailed the move. Forest finished 16th in the Premier League last season with 44 points (11W-11D-16L), and supporters are now questioning the club’s transfer strategy.

Why did the Diomande deal fall through?

Talks stalled over Sporting’s asking price, despite Forest’s push to strengthen Glasner’s preferred three-at-the-back system. Diomande, tipped to become a world-class centre-back, would have slotted perfectly into the Reds’ defensive setup. Yet, with the window closing, the clubs failed to bridge the financial gap.

How are Nottingham Forest fans reacting?

Social media erupted with frustration, with one supporter branding the club the 'worst on the planet at buying players.' Owner Evangelos Marinakis faces pressure after only two signings this summer: Xaver Schlager and Gustavo Sa (the latter immediately loaned to Olympiacos). The collapse follows a pattern-Arsenal and Manchester United faced similar 'last-minute' hurdles with Sporting before sealing deals for Viktor Gyokeres and Bruno Fernandes.

Is there still hope for a late revival?

History suggests Sporting may yet reopen negotiations, but optimism is fading. Forest’s recent form (DDWWW, unbeaten in five) and last result-a 1-1 draw with Bournemouth on 24 May 2026-offer little distraction. With the new season approaching, Glasner’s squad depth remains a concern.
