Bayern munich taught chelsea a harsh lesson admits lampard

I think there may be some mistake here!

Bayern Munich did indeed defeat Chelsea in the 2020-21 UEFA Champions League quarterfinals, winning 4-1 on aggregate. However, I'm not aware of any quote from Frank Lampard, the former Chelsea manager, admitting that Bayern Munich "taught Chelsea a harsh lesson".

If you could provide more context or a specific quote from Lampard, I'd be happy to help clarify or correct this information!
