Arsenal boss Arsene Wenger has said that Chelsea were "remarkable" in defence during their Champions League semi-final clash with Barcelona.

Blues centre-back duo John Terry and Gary Cahill managed to hold the defending champions out at Stamford Bridge, keeping a clean sheet ahead of the return leg on Tuesday night in Barcelona.

"Gary Cahill and John Terry had a great game," he said.

"The two of them blocked some shots from [Lionel] Messi and were remarkable sometimes. Drogba did the rest.

"Chelsea had a gameplan that worked."

Arsenal welcome Chelsea to the Emirates Stadium this afternoon.
