Muhammet Sinan Keskin (born 13 August 1994) is a Dutch-Turkish professional footballer who plays as a midfielder.
Born in The Hague, Netherlands, Keskin began his career in the youth ranks of local side Lenig en Snel. He then transferred to local Haaglandia before being recruited to join the Ajax Youth Academy.
In his first season with Ajax, Keskin played for the Ajax A1 youth squad, helping the team to the finals of the NextGen Series, the Champions League equivalent for under-20 youth squads at age 18. Ajax lost the final to Inter Milan 5âÂÂ3 on penalties after extra time, following a 1âÂÂ1 draw in regulation time, and finished the tournament as runners-up. Keskin remained in the A1 (under-19) team the following season before he was promoted to the reserves team Jong Ajax a year later. On 27 January 2014, he made his professional debut for Jong Ajax in a 2âÂÂ1 win over FC Oss in the Eerste Divisie.
On 19 May 2015, it was announced that Keskin had transferred to FC Utrecht.
Keskin holds both Turkish and Dutch citizenship and is still eligible to represent either team internationally. He was first called up to the Turkey national under-18 team for a friendly match. Keskin then appeared for the Netherlands national under-19 team in a 2âÂÂ1 friendly match win over Scotland on 10 September 2012. He has since pledged his allegiance to Turkey and made two appearances for the under-19 team.
