Lucas Leiva acknowledges Liverpool would not require comebacks like Saturday’s at Norwich City if they defended set-pieces better.
Liverpool eventually beat Norwich 5-4 at Carrow Road after coming back from 3-1 and then netting an injury-time winner in a thrilling encounter.
Their defensive flaws, however, were once again clear to see.
“If we can score five goals and defend set-pieces especially a little bit better, we would be winning games more comfortably,” Lucas said.
“Of course, we are happy to get the result, especially the way it was at half-time.
“The manager just said we had to find a way to win. We did it. Of course, it’s not the best way to win a game but maybe it was what we needed.
“We need to improve a lot but the passion, determination and belief is there. Hopefully, we’ll improve in things we’re not doing so well now and then move on.
“It’s better to win the game but we know we have to improve. But it will give us a lot of belief. On Tuesday we have a very big game, a semi-final and a chance to go to Wembley. We will do everything we can to get there.”
