The Blues have always been a formidable attacking force with the likes of Hasselbaink, Zola and Gudjohnsen in recent seasons - the arrival of the likes of Adrian Mutu and Hernan Crespo has upped the ante for Premiership defences.
"They've got the backing and they've got some amazing players," said Dean.
"We don't know too much about Mutu and Crespo and that's the thing - you know what to expect from Hasselbaink and Gudjohnsen, their strengths, what they are good at - but we haven't faced these players before and we don't know exactly what to expect. We'll have to be ready for that.
"But I think teams will be determined to do well there, the same as it has been with Manchester United - we'll be no different.
"You know they have quality players but you want to compete with them.
"We all know it's a massive game for us, I'm sure it will be a good game and one we're looking forward to."
Dean Richards argues that the unfamiliar element of Chelsea's revolution will provide our biggest challenge at Stamford Bridge.
