Ousmane Diomande’s fiercely competitive spirit often led former Sporting Lisbon coach Ruben Amorim to step in between him and Viktor Gyokeres to prevent their heated exchanges from escalating during training sessions.
The duo’s confrontations became so intense that their participation in practice matches against each other was halted to prevent injury or flare-ups. Diomande and Gyokeres, now an Arsenal forward, frequently clashed physically and verbally on the field during drills. Mini-matches were particularly fraught with tension. As the talented Ivorian defender gears up to join Nottingham Forest in a significant £35 million move, he will once again cross paths with his former training adversary.
Their rivalry stemmed not from dislike but from an unwavering commitment to excellence, treating practice with the same intensity as official games or casual kickarounds.
Previously, Glasner had set his sights on Diomande as Marc Guehi’s successor at Palace back in January. However, a slow response led to Diomande renewing his contract until 2030 with Sporting, which included a hefty £68.5 million release clause. Now, in a turn of fate, the Austrian manager finally lands the defender in his current role.
The investment is seen as a savvy move for Nottingham Forest as they transition from last season’s back four to a back three. Diomande is well-versed in the 3-4-2-1 formation, having thrived under Amorim’s guidance at Sporting, which aligns perfectly with Glasner’s strategic plans.

Diomande has all the attributes of a defender capable of thriving in the Premier League. Not only is he fast and proficient on the ball but he thrives defensively thanks to his physical strength and solid 6ft 3in build.
In last season’s Champions League, he won 66 per cent of his duels and is a relentless battler. He does not make it easy for attackers. Erling Haaland learned the hard way in a Champions League group stage match two seasons ago, after Diomande marshalled him well throughout as Sporting thrashed Manchester City 4-1 in Lisbon.
His sprint speed will also be a valuable asset. Diomande possesses explosive recovery pace which will help Forest when defending with a high line. His ability to recover quickly will allow Forest to react more effectively when opponents look to exploit the space in behind during transitions. Glasner’s Palace side often relied on it with Maxence Lacroix; Forest are likely to be no different with Diomande.
He will feature on the right of Forest’s back three, partnering Murillo and Nikola Milenkovic, as an imposing centre back. In Glasner’s system, he will be given some license to carry the ball forward and play line-breaking passes – which he has the skill set to do.
But at 22 years old, he does lack a bit of wisdom and has been guilty of running himself into trouble with overconfidence in possession. He will need to learn to pick the right moments to carry the ball, but that should come with experience – especially under the guidance of a top-quality coach.
Those who have followed Diomande closely during his time at Sporting told Daily Mail Sport that while the Ivorian exhibits a relaxed aura on the pitch, it has sometimes worked to his detriment – suffering blips in concentration.
That said, he does have know-how beyond his 22 years – making 87 appearances in the Portuguese top flight, 18 in the Champions League, 12 in the Europa League and earning 16 international caps including one at this summer’s World Cup. He has silverware to show for it, too, winning the Portuguese top flight twice and the Portuguese Cup.
That was the precise reason he opted to join Sporting. The Portuguese outfit identified him while on loan at second-tier side Mafra from Denmark’s Midtjylland. Despite losing against Porto 3-0 in the cup, Diomande delivered a standout performance, drawing attention from the Sporting scouts. They passed a report to then-head coach Amorim, who immediately wanted to sign him.

‘We have to give credit to the people who discovered him,’ Amorim later said. ‘The scouting department showed me the player, and once I saw the details, it was immediately clear he was the one, whether he cost €500,000, €2m or €8m.
‘He had all the characteristics – the way he played with the ball, his speed. And then there were other details, like going to the Dragao with Mafra and looking as if he was out in the playground. We knew what was there.’
When the January 2023 window opened, Sporting did exactly that, signing him in a £14m deal which will also see them pocket 10 per cent of the profit on this move, around £2.1m. Diomande credits Amorim with his career development and later revealed that the moment he was aware of Amorim’s interest, he wanted to make the move because of his faith in young players.
In Portugal, it was widely accepted that Diomande would eventually depart for one of Europe’s top five leagues. There was a slight surprise, however, that he did not wait for an even bigger move, as they believe he is destined for Europe’s elite. For Forest, that is a wonderful coup – especially if he follows his expected trajectory, which could see his value double in 2-3 years. There is also belief that once the mistakes are ironed out, he has the characteristics to be a leader.
Diomande suits Glasner, will have resale value if a bigger club does come calling and already demonstrated signs of becoming a supreme centre back – it is no wonder Forest want to make him the first marquee signing of the Glasner era. And, for the record, Gyokeres and Arsenal come to the City Ground on October 17. Get the fireworks ready.
