Reaction'It's important we make this advantage count' - Robertson and Mane react to Benfica win
The Reds are in charge of the last-eight tie heading to Anfield next week, with Mane, Ibrahima Konate and Luis Diaz on the scoresheet at Estadio da Luz in Lisbon.
Konate and Mane put the visitors 2-0 up inside 34 minutes, and Diaz netted their third late on after Darwin Nunez had pulled one back for Benfica early in the second half.
Read on for BT Sport's post-match interview with Robertson and Mane...
Andy Robertson
"It was a tough game. We were obviously on top [in the] first half, created good chances, probably could have went in a couple more up.
"Then we wanted to keep it tight and unfortunately we didn't manage to do that. They obviously got a goal, which lifted the crowd, lifted them and they started winning balls, we started getting a bit sloppy and things like that.
"So, the third goal was big but there's definitely still work to do. He [Diaz] got a nice reception from the start, obviously playing for one of their rivals and things like that. So, a good finish from him, a really important goal for us. It gives us a two-goal cushion, which makes a difference, and it's important that we make that count now.
"Next week, it's still a big game. We want to be in the semi-final and we've still got a lot of work to get there. But with our fans at our stadium, we can hopefully get the job done."
Sadio Mane
"Like I always say, the team is winning – that's more important [than me scoring]. I scored a goal today, I'm happy but more important were the goals we scored. We're waiting for the next game and to get the job done at home.
"A great start [to the week]. We can't expect better than that and it will help us to prepare for the next game."
