Champions League Ref Watch: Every appointment for this week's last 16 fixtures

If you are a regular visitor of BettingOdds.com then you will be aware that each week we bring you a lowdown of the upcoming referees for every gameweek in the Premier League.

In our Friday column we list every official taking charge of a top-flight game across the weekend alongside their key stats, including: appearances, yellow cards per game (pg), red cards and penalties awarded. 

This can help you out when you're picking your bets for the action as you'll be able to reference our list to get all the information you need quickly and hassle-free. With the Champions League last-16 returning this week, we thought we'd extend Ref Watch beyond the Premier League and into Europe's most prestigious knockout competition.
