Liverpool manager Jurgen Klopp explained one of his substitutions on Sunday.
The Reds picked up a valuable three points away from home in the Premier League.
Despite being 1-0 down and a man down against Newcastle United, Klopp's team won 2-1 thanks to two late Darwin Nunez goals.
Asked about substituting defender Joel Matip for Jarell Quansah, Klopp told reporters: No, no. The big man looked a bit tired, let me say it like this. It is long ago the boys now played a full 90 minutes, these kind of things. Joey played obviously 70 and we have Quansah.
It's great. He's a real talent. He played two really good passes, super-important passes, I would say. Defensively we needed luck a little bit, we were a bit too deep, a bit too passive, they could shoot but we have Ali.
There were, obviously, besides the result a few nice stories and bringing Quansah on is one of them."
