It's been an unusual season for Arsenal signing Sead Kolasniac. Arriving with a reputation for being the best left-back in the Bundesliga during his final campaign at Schalke, the 22-cap Bosnian initially impressed with a strong run in Arsenal's starting XI.

But the 24-year-old hasn't actually made a start in any competition since the end of December, first finding himself replaced by prodigious 20-year-old Ainsley Maitland-Niles and then Arsenal's veteran left-back Nacho Monreal - which all begs the question of who the Gunners' best option at No.3 actually is.

So, with a huge clash against north London rivals Tottenham due on Saturday, who would you start at Wembley this weekend? Would you opt for Kolasinac's brutish power, Monreal's vast experience or Maitland-Niles, who can inject some of that all-important academy product magic into the derby?

Let us know which left-back you think is Arsene Wenger's best option this weekend by taking part in the poll below...
