It's good they at least secured a win in the first leg. It will give them more confidence and a upper hand in the second g. It will be worst in Juventus tries playing defensive style of football cuz the sporting club I know is a dreadful attacking side. The reason why the match became a. Bit difficult for juventus was the defensive pattern Allegri turned to play after the first goal. I know it's possible, sporting may bounce back, but it will be difficult if juv should play their best pattern of football.
Agree with what you say because of course playing defensively in this match is tantamount to letting Sporting do everything in attack and this will not be easy for Juventus to endure if they apply this style.
They have to keep trying to balance and even have to try to dominate in midfield and of course this will be far more worth it than having to stay there.
