InterCity, promoted to the third division last season, came from behind three times to force extra-time after a 3-3 draw at the end of 90 minutes, but were then knocked out when substitute Ansu Fati netted a 103rd-minute winner in Alicante.
Ronald Araujo, Ousmane Dembele and Raphinha were Barcelona’s other scorers while the 21-year-old Soldevila netted his three goals in a 25-minute second half spell including a dramatic third in the 86th minute to take the tie to extra-time.
Soldevila spent two years at the Barcelona academy before moving to England for two seasons at Birmingham City, where he failed to break through into the first team.
