While Verstappen and Perez are currently team-mates at Red Bull, the team’s reserve driver Ricciardo is aiming to return to the grid next year, potentially with Red Bull-owned AlphaTauri.
Perez had a strong start to the 2023 season, taking two race wins, but Verstappen soon outstripped the Mexican and now holds an 81-point lead.
While many have speculated on Perez making an exit from the team, nothing has been confirmed to show that his time at Red Bull is set to be shortened.
Verstappen has shown little sympathy towards Perez’s struggles. Ahead of the British Grand Prix, he said: "Obviously we're also fighting for the constructors' championship win, but I think I'm going to have to do it on my own at the moment."
He also suggested that Ricciardo is ‘comfortable’ with the team, though he refused to be drawn on whether Ricciardo could replace Perez.
Verstappen said: “Daniel is doing a good job in the simulator, which doesn't surprise me either, because he hasn't lost his talent. I think he's comfortable with us."
He added: "He listens a lot and asks a lot. I know Daniel very well, so we can talk about a lot of things."
As for the fact that he could replace Perez, Verstappen said: "I don't talk about that."
