Arsenal have been linked with a move for Eintracht Frankfurt defender Evan Ndicka. Mikel Arteta and Edu are eyeing a left-sided centre-back in order to provide healthy competition for Gabriel Magalhaes.
The Gunners had made a bid for Lisandro Martinez in the summer before the defender opted to move to Old Trafford. The plan was to predominantly play the Argentine at left-back but have him available as competition in the left-centre back role. Whilst Takehiro Tomiyasu can do exactly that, he isn't naturally left-footed, which means Edu is still on the hunt for someone to properly rival Gabriel in that position.
Ndicka was incidentally touted with a move to north London in the summer, with Arsenal's rivals Tottenham believed to be interested. Nothing of note materialised, but the Gunners should be better positioned to rival Spurs for his signature if they revisit their interest in the near future.
