It was an important moment for Alaba, who has struggled with injury for almost the past two years.
The Austria international said afterwards: “I'm feeling great, ready to play 90 minutes like today. I'm pleased to have played 90 minutes and I’m feeling good.
“This was our goal. After the match at the weekend, our reaction was very important. Today we played very well, very professional, it was top class."
On Kylian Mbappé's hat-trick in the 5-0 win, Alaba added: “He's a very important player for us. He's the best player in the world. Every match, he creates chances and runs a lot for us.
"He's very important on the pitch, but also off it. We're delighted to have him in our team.”
