Barcelona are due to take on Real Madrid tomorrow night in the second leg of their Spanish Super Cup clash.
The Catalan giants slumped to a disappointing 3-1 win over their fierce rivals at the weekend.
Their poor performance showed the need to sign a replacement for Neymar, who left for Paris Saint-Germain in a world-record £198million transfer deal earlier this month.
And, speaking ahead of their clash against Madrid, Busquets has called on Barcelona chiefs to replace the Brazilian.
“Replacing Neymar is a priority,” he said.
Two names being tipped to fill the void left by the 25-year-old’s departure are Philippe Coutinho and Ousmane Dembele.
The Liverpool and Borussia Dortmund stars are highly rated by Nou Camp chiefs.
And Busquets has admitted he would welcome both players over in Catalonia.
“Coutinho and Dembélé? Who ever comes will be welcome,” he added.
“We lost a lot offensively without Neymar.”
Another player being backed to leave Barcelona this summer is Sergi Roberto.
Both Manchester United and Chelsea are supposedly keen to sign the Spain international.
But Busquets thinks he remains an important player for Barcelona.
“If I were a coach, would I start Sergi Roberto? I’m not a coach. Sergi is a player the team needs,” he said.
