Chelsea became the first team to prevent Barcelona scoring at Camp Nou this season with a scoreless draw in the CL semi-final first leg. The Spanish League leaders dominated for long periods but failed to breakdown an obdurate Chelsea defence in which John Terry was outstanding.
On those occasions Barca did find a way through Petr Cech made some fine stops from Thierry Henry, Bojan and Alex Hleb.
In fact the visitors could have nicked a valuable away goal had Didier Drogba and Michael Ballack made the most of Chelsea's limited opportunities.
Terry admitted to ITV1 that whilst they may have shut-out Barcelona this time, the Spanish side are still a class outfit.
"I'm not too sure what we did right but they still had a few chances. But we kept it tight and had watched videos of them of how their wide-men come inside.
"I wouldn't say we worked them out because they still dominated possession but to get a result here is a fantastic performance.
"Now we get them back at the Bridge with a fully fit squad and the crowd behind us."
