Barcelona are boosted by the return of duo Xavi and Daniel Alves to the squad facing Stuttgart in the Champions League on Tuesday. The duo was struggling with injury and missed Barca's weekend Liga victory over Racing Santander. Striker Zlatan Ibrahimovic, who has an ankle injury, has also been included in the trip to Stuttgart. Ukrainian defender Dmytro Chygrynskiy misses out as he is ineligible to play in a European competition due to his earlier participation with old club Shakhtar.
