Arsenal are most likely to face La Liga leaders and Champions League holders Real Madrid in the last 16 of this season's competition.
According to statistician Constantinos Chappas, Arsene Wenger's men have a 21.7 per cent chance of meeting Cristiano Ronaldo and Co in the first knockout stage.
That's almost two per cent more than Spanish outfit Sevilla and almost nine per cent more than Benfica, who are the side least likely to come up against the Gunners.
Wenger had hoped that finishing top of Group A would result in an easier draw, but he now faces the prospect of meeting Zinedine Zidane's in-form side.
