Frank Lampard admits injuries and lack of signings will affect Chelsea to some degree this season.
The 41-year-old was speaking after Sunday's 4-0 loss to Manchester United.
The Blues were unlucky to be down at half-time but were ultimately blown away by a far more clinical United, and Lampard wants to see rapid improvement from his side.
Speaking to the club's website, Lampard said: "In terms of the squad we know we couldn't bring players in this summer. I believe we have really talented young players.
"Let's be clear: with the injuries we have at the moment, and not bringing in players, this is going to be a work in progress to a degree. We will have to learn harsh lessons and correct them pretty quickly.
"We will bounce back from this. It should hurt. We certainly don't want to lose anywhere 4-0, and it hurts, but this isn't a 4-0 like any other.
"We certainly shouldn't let it consume us to the point it has any effect on us going forward, other than analysing the mistakes and correcting them."
