Liverpool striker Sturridge did not take a spot-kick as the Reds lost 3-1 on penalties.
Jurgen Klopp revealed it was impossible for Daniel Sturridge to take a penalty in the Capital One Cup final shoot-out loss to Manchester City on Sunday.
According to Klopp, the England forward "couldn't walk" to take a penalty as Lucas, Philippe Coutinho and Adam Lallana all missed theirs in the 3-1 shoot-out defeat at Wembley.
Emre Can was the only Red who scored his penalty which was the first following a 1-1 draw after extra-time.
However, Klopp told Sky Sports: "We asked the players and these five players said 'yes'.
"There was no chance Daniel could take one. He had cramps in the last few minutes. He couldn't walk. Everyone who was available took the penalty."
The German added: "You need a bit of luck, but you need to shoot a little bit better than we did. They know how it works and today it was not too difficult for their goalkeeper.
"Simon Mignolet was close to the ball a few times. That's how it is and we have to accept it.
"I feel disappointment, because it was a great day until the last shot. We were perfectly organised, and it was a perfect atmosphere, and a great experience until then.
"We tried everything. I can be proud of a lot of things but to be honest I expect we can do these things, so it's not easy to be proud of things you think is normal."
