Juventus fullback Danilo admits frustration after their 2-1 defeat at Champions League opponents Porto.

The defeat leaves Juve an uphill challenge for the second-leg of this round 16 tie.

“This is the Champions League, we knew it was going to be a tough game against a team that works really hard and prepares for this type of fixture. We certainly cannot go around gifting them goals the way we did tonight," Danilo told Sky Italia.

“This is not the game we expected. Maybe we need to remember that games start from 0-0 and the first minute, so we woke up too late.

“After that, it's difficult to regain your confidence, as they seem to reach every ball first and it's a struggle to find spaces."

Danilo was booked and will be suspended for the second leg.
