Constantin Grameni

Viitorul Constanța / Farul Constanța

Grameni made his professional debut for Viitorul Constanța on 4 April 2021, in a 0–1 Liga I away loss to Botoșani. He became a first-team regular after the club merged with Farul Constanța in the summer of 2021, amassing 30 league games in the 2021–22 season. On 17 February 2022, Grameni scored his first and only goal of the campaign in a 8–2 Liga I thrashing of Academica Clinceni. On 31 August 2022, Grameni netted a goal in a 3–1 Liga I home defeat of FCSB. In the 2022–23 season, he collected six goals from 39 appearances to aid his side in winning the national title. Shortly before the conclusion of the championship, fellow league club Rapid București submitted a €1 million offer for Grameni, which was deemed too low by Farul president Gheorghe Popescu. Grameni made his debut in European competitions on 18 July 2023, starting in a 0–3 away loss to Sheriff Tiraspol in the UEFA Champions League first qualifying round.

Rapid București

On 8 September 2024, more than one year after its initial bid, Rapid București transferred Grameni on a three-year contract with the option of another year for €400,000 and 30% interest.

Grameni was selected by manager Emil Săndoi in the Romania under-21 squad for the 2023 UEFA European Championship, but missed out on the final tournament after being ruled out with an injury.
