Lazio midfielder Matteo Guendouzi insists they should be calm after their Champions League defeat at Atletico Madrid.

Atletico won 2-0, though both teams have reached the round of 16.

Guendouzi said: "We knew it would be a difficult match, it's a defeat against a great team.

"Except for the goal conceded at the start, Lazio were there and we still have to take the positive aspects. I feel good, it's not easy to say after a defeat, I'm understanding (Maurizio) Sarri's schemes and I will work to do more and more.

"Which team would we like in the round of 16? We will face great teams, it will be essential to believe in ourselves and give our best."
