The veteran midfielder admits they feel well in the mix for this season's title race.
"When you look at our squad, one Premier League title in seven years just doesn't feel right for Chelsea," Lampard told Sky Sports.
"But there is a real feeling that things are fitting into place under Jose Mourinho. We had a mentality from Jose's first time at the club that coming second was a disappointing year. That's the way we regarded it.
"The last two years have been the worst two in recent memory in terms of league performance although obviously we've done really well in Europe.
"But coming sixth and third domestically doesn't feel good enough. For those of us who are still here from Jose's first time in charge, we know what he is like week in and week out, and you can sense he is bringing that winning mentality back.
"It's what we need and it's for us, the players, to now show the consistency, which is what is happening."
