A pair of juicy Champions League quarter-finals are on the schedule for Wednesday, with two giants of the game going head-to-head.

Bayern Munich v Real Madrid is the most common meeting in the tournament's history and the Bundesliga leaders take on the LaLiga frontrunners again in Munich in the first leg.

The second of Wednesday's ties looks to be as exhilarating, with the latest chapter of Leicester City's incredible story to be written as the Premier League champions travel to last season's beaten Champions League finalists Atletico Madrid.

Diego Simeone's amazing record in the knockout rounds of the tournament will be tested by the Foxes, who lost for the first time under Craig Shakespeare at Everton on Sunday.

What can we learn from Opta's data ahead of the two ties? Here's the pick of the statistics.
