2023, Daniel for a much improved Alpine Team. probably with his salary paid by McLaren.
That is a likely outcome and definitely the best option for Daniel if he wants to stay in F1.
Other options include, McLaren paying his salary (15 to 21M depending on media source) and McLaren farm him out to one of the vacant seats:
Williams. The new owners may surprise with their new car and they do have Mercedes power, which was the benchmark. They would love a Free driver that is a proven winner and have a vacancy.
Haas. Their 2023 car is being developed, in a separate office at the Ferrari complex , using Ferrari staff on secondment, Surely they have to do better and need an experienced driver. Daniel could get McLaren $$$$ plus a bonus from Haas. They would love a Free driver that is a proven winner. Their current drivers are not really up to the game, surname regardless. Of course, that is if they remain Haas, nd not Andeetti/Hass.
There is still the option of Indycar (which I would choose) or sports car racing. all under the McLaren management.
Whatever happens, McLaren is not a happy place for Daniel. Please take the $$$$ on offer and get another drive. Let's face it McLaren is not a winning team and if you must go to a non-winning team, choose to change, but take the $$$$ with you.

There are a lot on options in the McLaren camp and none of them are good for Daniel, or probably for a swag of other McLaren signed drivers.
