The Blues have lost twice this season, away to Everton and Newcastle, and Lampard says people need to realise that the team is evolving in Mourinho's second spell.
Lampard told The Sun: "Of course people need to realise it's a different scenario. If you can't see that then you can't really see straight.
"It is completely different from when Jose was here before. We had a very strong group that was ready to win a league. It was the perfect storm that came together for us."
