That's true and even in the second leg Sporting will have a higher chance to beat Juventus because they are playing the game in the José Alvalade Stadium which is Sporting's stadium where they can have a better situation than the first leg and they can have a higher chance to beat Juventus because the 1-0 lose was not really for the first leg.
actually they were able to take advantage of the situation to host in this second leg. juventus only has a slim advantage and it is certain that the second leg meeting will display a more aggressive performance from the host to catch up on goals in this second leg. I believe that Sporting can turn things around in the second leg but on one condition they must be able to control the game from the first minute to lift the players' enthusiasm to score early.
one side this is a match that is quite meaningful for juventus because they only have one hope of getting a trophy this season, namely the Europa league. the advantage of the first leg will be the capital for Allegri men to provide a more interesting match at Sporting cage.
Although many people say that Juventus will be stopped when they travel to Portugal, I feel confident that the Old Lady will be able to qualify for the semifinals. The 1-0 advantage in leg 1 is an important capital for Juve. But I'm a little worried if Allegri is not sensitive to the game in leg 1. It must be admitted that Juventus' game was very bad and failed to dominate even though they were the hosts. But I'm sure Allegri has done an evaluation and he is very ambitious to bring Juventus to the semifinals and even become a champion.
