Lamine Yamal scores twice as Barcelona maintain perfect start

However, Hansi Flick's side held their nerve and sealed all three points in second-half stoppage time when substitute Karim Adeyemi fired past Matthew Ryan to restore his side's two-goal cushion and seal an important win.

But the home side were handed a lifeline when Barcelona began to lose their focus and composure, allowing substitute Ivan Romero to pounce on a defensive error from Espart and pull one back with 11 minutes remaining.

The defending champions appeared to be cruising towards a fifth-consecutive league victory when Lamine Yamal scored his second goal of the game, and Barcelona's third, from the penalty spot just three minutes into the second half.
