Juventus will sporting flat and clean, I will not even doubt it whether Sporting won Arsenal, in football weak teams are also doing well in some cases and not all. The last recent concluded world cup tournament at Qatar shown the best way in football. Football in these days is not like those days. Even though Juventus is good in the Europa League and Serie A football tournaments, Sporting is also good other leagues. We can also see this differences in the Liverpool and Manchester United in the premier league and also what happened to the both teams in the championship game and La Liga. In these days, football cannot be predicted. Football now is taking a new dimension, that is the weak are getting strong.
But in other ways, this could also be a surprise again, especially for the Europa League, there are always some surprises that often occur if you look at the previous season.
Juventus' current condition is the same as Arsenal's previous condition which was the favorite, but that is not a real guarantee either for them to win easily.
The hope is that they win but this will not be an easy game for them especially with Sporting's defense against Arsenal being really good.
