Fair play to Sven and the Blues, we weren't afraid to have a go at Chelsea, but that proved to be our undoing as the home side killed us on the break.
We gave the ball away far too often and as Chelsea charged forward, they cut through our defence with ease. The back four were exposed but they were often out of position too, particularly left-back Javier Garrido - maybe it's time to give Michael Ball a recall.
"We were taught a lesson," said Sven. "It's good to play good football and to attack, but when you lose the ball you have to do much better than we did.
"I'm sorry for our performance, I'm sorry for the fans who travelled down and hoped to see us play good football.
"I think we started OK, but if you are not prepared to defend much, much better than we did today, things like that happen."
Michael Essien and Didier Drogba gave Chelsea a 2-0 half-time lead before City capitulated in the second half, with Drogba scoring a second.
Joe Cole and Kalou also got in on the act, and as one Chelsea fan put it on Radio Five Live, we were so bad that even Shevchenko scored too.
"Of course it's very bad being 2-0 down at half-time and trying to get it right. Then after 3 and 4, the heads were very much down and we came off even worse, that's not good. I hope that we have learnt something," Sven added.
"You can't give them the possibility to have so much space and time. 5 of the 6 goals they were alone with Joe Hart and if you allow that in 90 minutes, it's very bad.
"Nothing has changed, it is just a very good reminder that this is not good enough and that is it."
