Jurgen Klopp had no regrets about selecting a youthful side as Liverpool were held to a goalless draw by Plymouth Argyle in the FA Cup at Anfield.
Klopp told BT Sport: "It's not the result we wished obviously but it's not frustrating because that's football.
"We started well, we played football with direction and had movements but that's not a fine-tuned side today so that means they lost their patience too early and tried to force it – this team could have played much better today. We go to Plymouth for the first time in my life, all good.
"The whole of Plymouth was in the 18-yard box! You need to stay calm, you need to stay patient in these situations - that is the biggest challenge in football against a deep defending side for all teams in world football."
