Shakhtar Donetsk breathed life into Group H with a 1-0 win over Barcelona.
Barca went into the game knowing a win would guarantee their progression to the knockout stages with two games to spare, but they were extremely disappointing in slipping to defeat at the Volksparkstadion.
Danylo Sikan’s header on 40 minutes was worthy of winning any game as Shakhtar opened up the group.
Shakhtar began brightly, and Marc-Andre ter Stegen had to stand tall to deny Mykola Matviyenko.
