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.
