Liverpool boss Jurgen Klopp was delighted with goalkeeper Adrian after victory over Brighton.
Leading by two goals thanks to Virgil van Dijk's first-half headed brace, the Reds lost Alisson to a red card in the 76th minute after he handled outside the box.
Adrian was subsequently thrown on, but failed to touch the ball before it nestled in the back of his net from a clever Lewis Dunk free-kick.
That goal proved the catalyst for Brighton to dominate the closing stages, though they failed to turn possession into goals as the hosts held out for the win.
Reflecting on another difficult test passed, Klopp said: Life became more complicated with the red card and the change we had to make.
We brought on a frozen goalkeeper, pretty much. Everybody sitting here is probably not warm yet and then you imagine you go on there with shorts and a really thin shirt and some gloves that are not made for keeping you warm.
Then, some people let the free-kick happen like that - you look a bit silly in that moment, that's what you have to accept.
But we kept on fighting and Adrian especially helped us a lot with two really, really good saves and crosses he caught and stuff like this. But with his cold feet he couldn't kick the ball as far as he wanted.
"That kept it a bit interesting but at the end it's so important that we won the game and that's what we did, so I'm really pleased about that."
