Inter Milan include Balotelli, Sneijder for Barcelona
Also included is defender Davide Santon.
Sneijder has won his race to be fit in time after struggling with a thigh strain over the last two days.
Balotelli's candidacy was also in doubt after his antics during last week's first leg, which were roundly criticised.
The 19-year-old reacted badly to boos from the crowd and shouts from Mourinho, throwing off his shirt at the final whistle.
