The Hammers boss has been discussing the similarities and differences between both sides.
And the 60-year-old says the key difference between both teams is that the Hammers have far more strength in depth.
"We were flying at Bolton at that time and were very close to getting where none of us expected," the West Ham boss told reporters on Friday.
"The prospects we have now is that this is a bigger squad than that one and has more strength in depth than this one. It has not quite got the experience but we have a lot of strength in depth and in the deeper end of the squad we have a lot of good players to step in when needed.
"That was not the case at Bolton. We had a strong 14 or 15 but nothing more than that. That is why it never lasted at Bolton, sadly."
