Seny Dieng

Early career

In July 2011, Dieng signed for Grasshoppers from Red Star Zurich. In November 2012, Dieng made his debut in adult football at the age of 17, for FC Grenchen whilst on loan from Grasshoppers. He signed his first professional contract with Grasshoppers on 1 August 2014. On 5 August 2014, Dieng was named on the bench in a 3rd qualifying round Champions League match against Lille. On 2 February 2016, aged 21, Dieng signed for MSV Duisburg on a free transfer but relegation to 3. Liga meant he was released months later without having made any appearances. Dieng left for a career in England where he went on trial with AFC Fylde, Rochdale and Barnsley.

Queens Park Rangers

On 26 August 2016, Dieng signed for Queens Park Rangers on a free transfer until 2018. On 3 July 2019, Dieng signed a new two-year deal with QPR, keeping him at the club until 2021.

Loan spells

On 2 December 2017, while playing for Whitehawk (in National League South) on loan, Dieng scored a goal in the 91st minute of a game against Chippenham Town. Going up into the Chippenham box for a late corner, he headed in from 8 yards. Dieng spent the first half of the 2018–19 season, on loan at Stevenage, making his debut on 14 August 2018 in an EFL Cup match against Norwich City. On 10 January 2019, Dieng joined Dundee on a loan deal for the remainder of the 2018–19 season. On 26 July 2019, having still not made a senior appearance for QPR, Dieng went out on loan again, this time…

In May 2014, Dieng received his first call-up for Senegal for their friendly against Colombia, remaining on the bench for the 2–2 draw. Dieng was again called up to the Senegal team in March 2021 and made his debut on 30 March in a 1–1 draw with Eswatini as Senegal qualified top of 2021 Africa Cup of Nations qualification Group I . Dieng was subsequently named in the Senegal squad for the 2021 Africa Cup of Nations and following a positive test for COVID-19 from first-choice goalkeeper Edouard Mendy, Dieng started in Senegal's two opening matches. He kept a clean sheet in each of those appearances, actions proving to be vital given Senegal only managed 1 goal throughout the entirety of the group stages before going on to win the tournament, beating Egypt on penalties. Dieng was non-playing member of Senegal's squad for the 2022 FIFA World Cup in Qatar. In December 2023, he was named in Senegal's squad for the postponed 2023 Africa Cup of Nations held in the Ivory Coast.
