Alonso joined Aston Martin for 2023 but his contract expires at the end of this season.
He has had ample opportunity to publicly declare his commitment to the team. But the 42-year-old has instead talked up his best-ever pre-season fitness test results, touted his marketing worth and highlighted that, of the three champions on the grid, he is only one available for 2025.
This has done little to quash speculation that Alonso is a frontrunner for a Mercedes seat to replace Hamilton when he moves to Ferrari, although there is plenty of momentum behind Silver Arrows protege, junior single-seater champion and FIA F2 rookie Andrea Kimi Antonelli.
Speaking on the final day of pre-season testing in Bahrain, Alonso reckoned he was in a "good position to negotiate" while adding he would let the early races of the new campaign play out before turning his attention to where he will drive for 2025 and beyond.
"In my case, it's very interesting because I have, I think, a good position to negotiate," he said. "But I want to at least do the first couple of races without thinking too much.
"I want to see myself into a new season. It's going to be the longest-ever season in Formula 1 [at 24 races].
