Liverpool boss Jurgen Klopp has explained the decision to take off Darwin Nunez and Diogo Jota on Wednesday.
The Reds needed many more goals to come back in their Champions League tie against Real Madrid.
Having been 5-2 down from the first leg, Liverpool lost the second leg 1-0 in Madrid.
Asked about the subs, a deflated Klopp said to reporters: For Diogo it was clear he shouldn't play extremely long as he is still coming back from a long, long injury and you could see the game got harder for him.
He made some fouls as he was coming late, so no risk for him.
Darwin looked like he was not at the absolute top level as well and we needed to defend that side as well. We could change and we wanted to mix things up a bit."
