MADRID, Oct 3: Celta Vigo took advantage of an early breakdown by Barcelona and the late blunder by Ter Stegen to hold on to its home victory.
Pique scored twice and Neymar once as Barcelona came close to rallying from the three-goal deficit, but the goalkeeper's mistake with the game at 3-2 dampened the team's chances.
Instead of sending the ball into attack, the German goalkeeper tried to pass it to a defender, but Celta midfielder Pablo Hernandez timed his jump perfectly and the ball struck his head and hit the far post before crossing the line.
"We know Marc is very good with his feet, a lot of our plays begin with him," Pique said. "Everybody makes mistakes, but we know him well and he won't be affected by that."
