Our round-up of the Champions League Round of 16 sees Lionel Messi hitting two to push aside Arsenal, Cristiano Ronaldo scoring his 12th of the campaign in a victory over Roma, and Man City take a peek behind the door of the last eight for the first time in the clubs history.

Barcelona remains the favourites to retain their Champions League crown after a comfortable victory over Arsenal at the Emirates in the Round of 16.

It seems the only way to play against Barcelona is to let them have the ball, hope the trident up front has an off day, and to capitalise on some sloppy defending at the back.
