Jürgen Klopp allayed concerns on the knock Alexis Mac Allister suffered during Liverpool's pre-season meeting with Bayern Munich on Wednesday.
The Argentina midfielder was withdrawn at half-time of the Reds' 4-3 defeat to the Bundesliga champions in Singapore after sustaining a minor blow to his knee.
Speaking at his post-match press conference, Klopp said: "Yeah, knee on knee. He could have played on.
"So firstly I got the information that it's too painful, so that was then clear that we will change. There's no need to push him through.
"When I spoke afterwards, he said, 'No, no, I would have been fine.' But we didn't want to go [with] any risks. It's just knee on knee, bruise, that's it. It was fine."
