Max Verstappen open to potential Daniel Ricciardo return to Red Bull amid uncertainy over Sergio Perez

Max Verstappen has cast further doubt over whether Sergio Perez will remain at Red Bull next season.

Perez's seat with the world champions is in the spotlight following his poor run of form and his first-corner exit at his home race in Mexico last weekend.

"All of the stuff round my contract next year has been related to AlphaTauri, and honestly, I would say that is as far as that goes.

"But having a weekend like Mexico was good for the soul. It was nice to have a weekend like that, but
