Arsenal can sign Real Liepzig defender Dayot Upamecano for £53m next summer.
The Gunners were strongly linked with the 20-year-old during the recent transfer window but were ultimately unable to agree a deal with the defender’s Bundesliga club.
Unai Emery’s side completed the shock signing of David Luiz from Chelsea for £8m on deadline day, but the Brazilian defender has so far endured an inconsistent start to his Arsenal career.
Reports in Germany outlined a £55million bid for Upameanco fell short of his release clause at the time, believed to be between £72m and £92m.
But the centre-half’s buyout, part of a contract running to 2021, is set to drop next summer.
A knee injury this season has held so far held the progress with the Frenchman only returning to action a fortnight ago.
The Gunners have already conceded 11 goals in 7 games so far this season – more than any team in the top six.
