The Liverpool boss named the club’s youngest-ever team for the home tie, even with the likes of Emre Can, Lucas Leiva and Alberto Moreno making the starting line-up, but despite dominating for the majority of the match, the Reds struggled to force Plymouth goalkeeper Luke McCormick into a meaningful save.
The German brought on internationals Daniel Sturridge, Adam Lallana and Roberto Firmino as his side looked to break the deadlock but it came to no avail as the club from the fourth tier became only the third team in a year to prevent Liverpool from scoring 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.
“As a manager you make a decision, you can criticise or whatever makes more sense for you, but all good.”
