Juventus fullback Alex Sandro says they must step up their game facing Champions League opponents Dynamo Kiev.

Juve have already reached the round of 16, but come off a disappointing 1-1 draw with Benevento.

“It's always difficult in the Champions League and tomorrow will be a tough match, because I know they studied our way of playing, but our mentality is to win and I'm sure we'll play well," Alex Sandro told JTV.

“I want to see a step up in quality tomorrow, in defence, the midfield and attack, because mentality makes the difference. We have to be concentrated from start to finish, because we often concede goals in the closing minutes of each half."

Alex Sandro is back in business after missing most of the season so far with injury.

“I feel better every day, I'm ready and at the disposal of the coach, so if given the chance, I'll give my all on the pitch."
