The Blues suffered a resounding defeat at the hands of their bitter rivals despite the west London side hitting the woodwork in the first half at Old Trafford.
Goals from Marcus Rashford, Anthony Martial and Daniel James sealed a comfortable victory for Ole Gunnar Solskjaer’s side in their Premier League opener.
Chelsea FC were heavily criticised for their second-half performance at Old Trafford in Lampard’s first Premier League game in charge of the west London outfit.
Lampard’s men lost to Liverpool FC on penalties in the Uefa Super Cup on Wednesday night after an entertaining 2-2 draw between the two sides after 120 minutes.
Chelsea FC will welcome Leicester City to Stamford Bridge in their next Premier League fixture on Sunday afternoon.
Speaking at his pre-match media conference at Cobham training ground on Friday ahead of the visit of Leicester, Lampard said:
“In terms of the Manchester United game, I think some of the criticism was quite lazy because it was a reaction to a 4-0 scoreline.
“Now I get that, I get that it was 4-0, we made errors, there should be criticism, I’d be the first to say that.
“But a lot of our general play was really good. So I’m not listening to that. I’m taking out the positives of that game.
“There were more positives against Liverpool, because I thought our performance wholly was really, really good and we need to now turn it into wins.
“I’m not interested in criticism from the outside. I’m interested in how we work every day and the team becoming the team I know we can be, and I have full belief in them.”
Chelsea FC added Croatian midfielder Mateo Kovacic and Borussia Dortmund playmaker Christian Pulisic to their squad in the 2019 summer transfer window.
The Blues finished in third spot in the Premier League table last season and won the Europa League title thanks to a 4-1 win against Arsenal in Baku.
