Petr Cech believes that Jose Bosingwa's performance at left-back was one of the keys to Chelsea becoming the first team to stop Barcelona scoring at Camp Nou this season.
The Blues' goalkeeper was impressed by the Portuguese international's ability to switch from his more familiar role on the right and then control Lionel Messi too.
While Barca were left to wonder what might have been, Chelsea were delighted with their defensive display and Cech was particularly pleased with those in front of him.
"The biggest compliment should go to Jose because I think it was the second time in his life that he played at left-back and it was against Messi," the Daily Mail quote him as saying.
"But you could not see Messi on the pitch today.
"John Terry was also fantastic and I have to say so were all the other guys because it is not easy to come here and deal with all their attacking threat.
"But John was the leader of the back-four and was brilliant. It is the first time we have got a clean sheet here but it is also the first time we haven't scored."
The Champions League semi-final tie will be decided at Stamford Bridge where Chelsea will have to open up while also ensuring that they do not concede at the other end.
"The tie is still open but I think we can reproduce the same defensive work at home and we can always score goals at Stamford Bridge,' he added.
"Of course They have the best attack in the world, so it still stays 50-50.
"We just had to stay organised and everyone had to put in great effort for the individual and tactical work."
