Many expected Barcelona to struggle this season after Luis Enrique stepped down as manager and Neymar departed for Paris Saint-Germain over the summer.
But the Catalan giants showed their mettle with a battling display against Getafe.
Paulinho incurred the wrath of many fans when he arrived from the Chinese Super League this summer.
But the Brazil international was the hero after he struck the winner in the 84th minute following good work from Lionel Messi.
It came after a tough contest where Getafe looked capable of pulling off one of the shocks of the season so far.

The hosts took an early lead through Gaku Shibasaki.
The Japanese international struck a thunderbolt past Marc Andre Ter-Stegen in the 39th minute, with the German unable to keep out his powerful drive.
It was a Suarez who then came to Barcelona’s rescue.
And not Luis, who again looked out of sorts.
Instead, Denis Suarez levelled in the 62nd minute, curling the ball into the top left hand corner after Sergi Roberto had pulled it back.
The win means Barcelona have now won all four of their first four games.
A feat not achieved since a certain Pep Guardiola was in charge.
They will be aiming to continue their stunning start when they face Eibar on Tuesday night.
