Jamie Redknapp believes that Frank Lampard should be very proud of the work his side put in against Chelsea.
Lampard's Derby were unable to progress in the Carabao Cup, but they did put up a spirited effort in the game they lost 3-2 at Stamford Bridge.
Redknapp spoke about that impressive performance after the game.
"There were a couple of big moments at the end when Richard Keogh and David Nugent nearly scored, but he will be so proud of his team with the way they played and the way they passed the ball," Redknapp told Sky Sports.
"He would have learned a lot about them today and they have come so far in a short spell under him. I thought they played really well today.
"They have got players who showed they will be more than capable of holding their own if they come up to the Premier League. But now they have gone out and they can concentrate on the Championship, which is what is so important now.
"Frank will be devastated that they have lost the game but now they can have a rest and go again in the league. The aim is to come up and play in the Premier League."
