Chelsea manager Frank Lampard has explained why the Blues suffered a 4-0 defeat to Manchester United in their opening campaign on Sunday at the Old Trafford.Lampard admits injuries and lack of signing has affected Chelsea to some extent.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.”Chelsea will face Liverpool on Wednesday for another cracker in the European Super Cup.
