Chelsea played the Mourinho's ugly style which is to def with all man and wait for counter attack... boring. Parked the bus since second half and they literally formed a pentagon around Messi

However I'd say Chelsea will regret defending too much because bringing one goal advantage to Nou Camp is just not enough.

That depends on personal perspective. For me Chelsea's defence was not that effective. If so we wouldn't be able to hit their post twice, and squandering other chances as well.
