So of course Sporting is unlikely to give up on Juventus in the second leg. They are playing at home, it is a good advantage to expect a great performance. Regarding the possibility of victory, it is still possible but it depends on how Juventus handle the resistance of Rúben Amorim's team.
Of course, they won't just give up in the second leg even though they lost in the first leg against Juventus. Moreover, their aggregate is only 0 - 1 so there is still a chance for Sporting to catch up or surpass it as long as they can optimize all opportunities, are more attacking, and also more accurate. This will be an exciting match because Juventus will not just give up. Moreover, this is a great prestige.
