Frank Lampard admits a chastening defeat to Leeds has offered him an early “reality check” during a first foray into management at Derby.
Having seen the Rams open the 2018-19 campaign with a dramatic 2-1 victory away at Reading, they were brought back down to earth with a bump in front of their own supporters on Saturday.
Tom Lawrence did briefly level for Derby after seeing Mateusz Klich open the scoring, but two efforts from Kemar Roofe and a fourth from Ezgjan Alioski eased Leeds to a convincing 4-1 win.
Lampard is no under no illusions as to the size of the task he faces at Pride Park as he endeavours to turn perennial promotion contenders into a Premier League outfit once more.
The Chelsea legend told Sky Sports after seeing his side demolished on home soil: "It's a reality check.
"We were really good in pre-season, and I kept saying it means nothing.
"We won last week in a tight game with some good stuff, but maybe we think the results in pre-season mean we were going to perform today and it doesn't. Every game we need to improve, and what better than looking back at this game, because there's plenty to look at.
"We can't be too depressed and too heads down as the games come thick and fast. We must learn from this and improve.
"The warnings were there, but we didn't react to them. It was 4-1 with 20 minutes to go, so I was looking to see the reaction. It was a real test for us in all senses."
While disappointed at the manner in which his side surrendered against Leeds, Lampard believes there are useful lessons for his team to take so early in the season.
The ex-England international added: "We were beaten all ends up and it's good lessons for us all. There's lessons for all of us to improve, getting beaten comfortably.
"Mistakes will cost you and pretty much all the goals were mistakes to a degree. We will have to go away and look at it. It's not nice in the first home game of the season, these results will happen, but it's the performance that we can't allow to happen, and that's something we must address."
