Sporting lost the first leg only 1-0. And so by performing well in the second leg, the team has a chance to qualify for the semi-finals. Moreover, the second leg match is Sporting's home match. It is expected that the players of Sporting will be more confident in the home match.
Juventus team is very experienced. They have a lot of talented star players on their team. However, their performance is somewhat erratic. However, if the performance of Juventus players is somewhat stable against Sporting, then it seems that Juventus will win. In addition, the Juventus team is considered the favorite in this match.
Overall, Juventus are the favorites, and what is a little doubtful about them is the inconsistency they often show. This is a home match for Sporting and usually the team that acts as the host will play all out, moreover they are only 1 goal behind in the first leg. I want to see what strategy Juventus will play in this important match.
The difference in quality between the two teams is big however is not a sure thing.Let us not forget the really bad performance of Juventus when they were beaten by a much weaker team than Sporting in group stages,Maccabi Haifa.Of course that was a different time and now Juventus has recovered a lot and they are enjoying a really good form in Serie A also where they have only lost against Lazio recently and have won all the other games they have played.
Sporting will be playing at home and they will have the fan advantage but we saw with Benfica vs Inter that Italian teams usually are much more pragmatic and as such for Juventus to qualify would be a really good bet.
