The Formula 1 driver market is buzzing with fresh speculation that could reshape the grid in the coming years. According to recent reports, Williams Racing's Carlos Sainz is being tipped for a sensational return to McLaren after the 2026 season, where he would once again team up with Lando Norris. This potential reunion hinges on a chain of events that starts with Oscar Piastri—currently McLaren's star driver—making a high-profile switch to Red Bull.

Sainz's journey back to Woking would mark a full-circle moment. The Spaniard originally raced for McLaren in 2019 and 2020, forming a memorable partnership with Norris that fans affectionately dubbed "Carlando." Their on-track chemistry and off-track camaraderie made them one of the most beloved duos on the grid. After leaving McLaren, Sainz enjoyed a successful stint at Ferrari, but that chapter closed when Lewis Hamilton took his seat for the 2024 season. Forced to find a new home, Sainz joined Williams—a team currently battling in the midfield. It was a tough decision, but one he made with an eye on the future.

Now, with his Williams contract reportedly running only through the end of this year, Sainz is looking for a way back to the front of the pack. Spanish publication Marca suggests that his strong personal connection with McLaren CEO Zak Brown—whom he often joins for rounds of golf—could smooth the path for a return. The appeal is clear: McLaren has reestablished itself as a top-tier contender, regularly fighting for podiums and wins.

But for this reunion to happen, the first domino must fall: Oscar Piastri would need to leave McLaren. And that's where Red Bull enters the picture. If Max Verstappen decides to walk away from the sport—or even just from Red Bull—after the 2026 season, the energy drink giant has reportedly already shortlisted Piastri as his replacement. Verstappen's growing interest in GT3 and endurance racing, combined with his dissatisfaction with the 2026 regulations and Red Bull's current struggles with the RB22, could all contribute to his departure. Red Bull team principal Laurent Mekies and managing director Oliver Mintzlaff are said to be prepared to move quickly if Verstappen signals an exit.

For Sainz, a return to McLaren would not only reunite him with a familiar team but also with a teammate who knows his style inside and out. The 'Carlando' era could be back, and with McLaren's current momentum, it could be even better the second time around. While nothing is set in stone, this potential musical chairs of drivers adds another layer of intrigue to an already dramatic F1 season. Keep your eyes on the paddock—the 2026 grid might look very different than we expect.
