Jurgen Klopp says he is not concerned by Daniel Sturridge's attitude after the striker was substituted in the 1-1 draw with Tottenham on Saturday.
Sturridge, 26, showed his frustration after being taken off in the 71st minute at Anfield to be replaced by Divock Origi, but Klopp revealed it was a tactical decision rather than anything to do with his recent fitness issues.
"I think that's completely normal, especially with the quality of Daniel Sturridge," said Klopp. "He has to think 'leave me on the pitch and I can decide the game.'
"That's true, but in this moment we need other help in the game. We needed ways behind the line. We needed Divock's physical strength so I changed.
"I could have changed Adam Lallana and gone with two strikers. But in my opinion, and only my opinion counts, it didn't make sense so that's it.
"I saw that he was not happy because I'm not blind. But that's not a problem because if he came off and [celebrated] something would be really wrong.
"You cannot play football with this confidence when you are like we are. You have to think 'yes, I'm the best.' I like this -- as long as he doesn't come off the pitch and do something really strange like kicking me from behind."
