I will watch Juve. both teams were fairly bad in first game, especially Lyon who managed to score somehow, but looked limited and simply couldn't keep the ball. they will have about 30% possession again, sit deep and try to counter but this time Depay will play which could make things interesting. Juve will be without Dybala, but at least De Ligt is back. I'm certain Juve will beat them quite easily, I'm just hoping it will be convincing enough for someone to score hattrick as I placed a bet on that. predictions: 4-1, 2x Ronaldo, Bernardeschi, Higuain - Depay.
as for City, I simply don't believe they will lose at home nor Madrid will outscore them. I predict a draw or narrow City win, something like 2-2 or 2-1.
