His side were beaten 2-1 by Manchester United in the Carabao Cup last-16, which saw the Blues fall to defeat for the first time in eight games.
A Marcus Rashford double cancelled out Michy Batshuayi's equaliser, after Lampard made six changes to his side that beat Burnley at the weekend.
Youngsters Billy Gilmour and Marc Guehi were drafted in, whilst Willy Caballero and Michy Batshuayi were all given minutes.
Frank Lampard was full of praise for his side despite the defeat, but has made his intentions clear, and insists it is time to focus on the 'big picture' which is in front of them which is prioritising their Premier League campaign.
"We’ve had seven wins on the trot, we’ve had taxing games in the Champions League. It’s important for us to get into the next stage of that." Lampard said on the Blues recent form. "We have a few tough games coming up.
"Our form in the league has been really good, and it’s quite clear they are the priorities. We want to win football matches and we want to give everything, but I have to look at my squad and people that deserve minutes, young players that are going to be big players.
"The competition has an element of that for us, and an element of wanting to win and be successful.
"I saw a lot of things that were good for us for the future, a lot of positives. I hate losing, we all do here, but it’s clear there is a big picture and there are a lot of big games for us to come and a busy fixture list. Now we move on and focus on what is to come."
