Former Tottenham midfielder Paulinho featured against Barcelona for Guangzhao Evergrande.
Tottenham pulled off somewhat of a coup in the summer fetching almost £10 million for midfielder Paulinho, with the Guardian reporting the fee at £9.9 million.
The Brazilian had been an expensive signing for Spurs under Andre Villas-Boas, with his addition pushed by then technical director Franco Baldini.
He lasted only two seasons, with his second a particular disappointment, failing to win over Mauricio Pochettino.
He decided to join Chinese club Guangzhao Evergrande, joining former England boss Sven Goran Eriksson and ex-Manchester City attacker Robinho.
At the weekend Paulinho scored a winner against Mexican side Club America which took Evergrande into the semi-finals of the FIFA Club World Cup... to face Barcelona.
Paulinho featured in pre-season as Evergrande defeated Bayern Munich on penalties in the Audi Cup, but there was no repeat here.
He won the competition with Corinthians in 2012, beating Chelsea in the final, this time around Barcelona displayed a more ruthless edge.
Even without the rested Lionel Messi they dispatched Evergrande comfortably, winning 3-0 thanks to a Luis Suarez hat-trick.
Paulinho lined up in central midfield alongside former Charlton and Celtic midfielder Zheng Zhi, playing all 90 minutes against Andres Iniesta and Sergio Busquets.
His performance drew a mixed display from those watching, while others were simply stunned to see him in action, unaware he was playing for the club. Here is a look at how Twitter reacted...
Spurs must've wondered if this was the Paulinho that they never saw.— Juan Arango (@JuanG_Arango) December 17, 2015
Messi won't be playing today due to abdominal pain. Maybe he just had butterflies in his stomach ahead of gracing the pitch with Paulinho?— Andrew Gaffney (@GaffneyVLC) December 17, 2015

Wondered where Paulinho had got to... still doesn't look any good though.— Ben Soro-Perez (@BFJSP44) December 17, 2015
Injury to Guangzhou player Zou Zheng looked pretty bad. Then Paulinho robbed Iniesta with consummate ease. Yep, you read that right.— Richard Martin (@rich9908) December 17, 2015
