For me it'll be a thing of joy if Sarri with his style of play can successfully manage Juventus into the champions league finals and possibly end the season by winning the trophy. Juventus are my pick to win this seasons competition. I would love to see Sarri win more medals as a manager especially via champion league as wining the SerieA medal is already assured. My picking of Juventus is simply based on emotiona (Ronaldo+Sarri) if I was to pick a team based on merit then I'll go for Liverpool.
Juventus yearn for the champions league every season, and the reason is obvious, they have totally dominated the Italian seria A in the last decade, and i do not see it coming to an end anytime soon.
Juve acquired the services of Ronaldo to see if he could help bring the champions league to juve but they were upset by Ajax, juve have a way of bottling it in the champions league, I think that will continue even with sarri's arrival.
My pick for the champions league is Real Madrid.
