The 19-year-old, tied to Werder Bremen until the middle of 2029, fits the profile of Arsenal's long-term recruitment strategy, according to a report by Fussballdaten.
Coulibaly is aware, however, that competition for his signature is fierce, with the young defender attracting interest from elsewhere in the Premier League.
Manchester United and Newcastle United have also been captivated by the German-Ivorian's performances, the same report states. Werder Bremen are seeking a club-record sale worth €50million for Coulibaly, meaning Arsenal would need to make a significant financial effort to beat their rivals to his signature.
Arsenal's pursuit of defensive reinforcements comes after a landmark 2025-26 campaign in which the club won the Premier League title, edging out Manchester City in the title race before losing to Paris Saint-Germain in the Champions League final.
Coulibaly, who stands at 1.91 metres, joined Werder Bremen from Hamburger SV in 2025 and has quickly established himself as one of the Bundesliga's most sought-after young defenders, earning recognition at German youth international level along the way.
He made 22 appearances in the Bundesliga last season, helping Werder Bremen avoid relegation and finish 15th, with his combination of physicality and composure on the ball drawing comparisons to some of Europe's most highly rated young centre-backs.
Beyond his three Premier League suitors, Coulibaly has also been linked with several major clubs across the continent in recent months, including Napoli, Paris Saint-Germain and Real Madrid, underlining the scale of interest in the teenager as he approaches what looks set to be a defining summer for his career.
