A furious Frank Lampard said he will not forget the things he learned about his Chelsea team after their toothless defeat at Sheffield United.
Chelsea travelled to Bramall Lane looking to tighten their grip on Champions League qualification but were outplayed in every aspect of the game as the Blades cruised to a 3-0 victory.
"They were better than us, they were stronger than us physically and with the ball, so you lose the game," Lampard told Sky Sports.
"You feel and hear every noise [on the touchline] and all I could hear was Sheffield United voices. They are a good team and if you come here and perform below par this is what will happen.
"We matched them shape wise but were too slow and weren't getting our wingers into the game. We tried to get control, which we did but weren't threatening.
"At 2-0 down you make it difficult for yourselves. Disappointing. Mistakes. You analyse all season and review and move forward. We need to put that to bed quickly and fight for the top four. I learned a lot and I won't forget that."
Chelsea remain third in the table after their second post-lockdown defeat, but victories for Leicester and Manchester United could see the Blues drop as low as fifth come Monday evening.
"I am not concerned about top four today," Lampard added. "Today I am concerned with how we performed.
"All I do is sit and watch the games and consider what we want to do. We will see where we are when we approach Norwich. But we can't approach Norwich or Manchester United or Wolves like we did today."
For Sheffield United and Chris Wilder, a fourth consecutive home victory saw them leapfrog Wolves into sixth place and move to within four points of Manchester United to give their Europa League hopes another big boost. ปิงปอง
"We were excellent, full value," Wilder told Sky Sports. "We had to defend properly, the structure of the team was good, and we needed something going the other way, and we did.
"It's been a tough schedule, and the quality of the teams we had at Bramall Lane needed turning over. I'm delighted we've turned Chelsea over.
"We're into a rhythm, I've really enjoyed watching my team play because they always give me the maximum they've got. As a manager, that is all you can ask for."
