Chelsea defender Gary Cahill enjoyed his clash with Arsenal skipper Robin van Persie for Saturday's 0-0 draw.

Less than three days after denying Lionel Messi and his Barca team-mates a goal in Wednesday night's Champions League semi-final first leg win, Cahill helped manage to thwart one of the world's other great forwards in van Persie.

The defender said: "It was great practice, coming up against the likes of Robin van Persie, who's in form this season, and is one of the best forwards in the world at the minute.

"It doesn't get any harder, does it, this week, facing the likes of Messi and then Van Persie and then back to Messi and the boys?

"So to keep two clean sheets in the two games we've just played is pleasing for us as a whole team."
