lots of speculation, but hey that's what we do here anyway

Option 1) Alexander Arbon Probably the first option Red Bull wants is to continue Alexander Arbon after 2020. If Arbon responds to the request of Helmut Marco, Red Bull's motorsport advisor in the remaining nine races, and if both drivers are able to show consistency with Ferrari in the constructors' championship, the possibility of Arbon's continuation will be high.
If Alexander Arbon can't match Max Verstappen to him, the team will have to look for other drivers. However, in the past, Danielle Kubiato was demoted in 2017 and replaced with Pierre Guthrie, so it is unlikely that Guthrie will recall it for the rest of 2019.
Option 2) Bring the former driver back to the team. The driver says they will never return, but Red Bull must do so. Are you going to recall Carlos Sainz ’s impressive performance after McLaren's move? Maybe, but by doing so, Red Bull has to admit that he has made a mistake, so it is unlikely that he will recall Sainz. Sainz is also very happy with McLaren and the team has already announced it as part of the 2020 lineup, so it is doubtful that Sainz will leave the team.
What about Daniel Ricardo? Daniel Ricardo, who wasn't very successful in his first year at Renault, might have expected it to be a pretty challenging season, but he wouldn't have expected it to be so bad . Daniel Ricardo has a contract with Renault in 2020, but may want to transfer. But Red Bull will have to pay a lot to cancel the deal with Renault.
What about the return of the rumored Ferrari Sebastian Vettel? Vettel has won four titles in Red Bull in the past and has a good relationship with his former colleagues. However, like Ricardo, in order to return Vettel, Ferrari, who has a contract for next year, must convince the release. Vettel has so far not been able to win a title in Ferrari, but has the impression that he is still patient.
Realistically, Red Bull's former drivers are out of stock. What about the connection with Honda? At present, only Takaki Yamamoto (age 31) is eligible for a super license. Due to Naoki Yamamoto's age, F1 experience and no racing experience in Europe, Red Bull will not bet on Naoki Yamamoto. Honda's other drivers, including F2's Shinji Matsushita, are not automatically selected because they don't have enough super license points.
Option 3) Search from outside the Red Bull family <br /> Red Bull may have been doing something since Mark Webber in 2007, that is, looking for drivers from outside the Red Bull family. Earlier this season, Nico Hulkenberg was named as a candidate for the replacement of Pier Guthrie. This year, Hulkenberg was not very active, and Esteban Okon's transfer to Renault has been rumored, and it is unclear whether Hulkenberg will remain in Renault after this season.
The Red Bull family once showed an interest in Land Norris and tried to hire it in Toro Rosso, but McLaren surrounded Norris. Will there be drivers suddenly like Sergio Perez that Ferrari and McLaren have been interested in? Sergio Perez says he wants to remain at the racing point, but the temptation to compete with Red Bull for a car will be difficult to reject. Similarly, Red Bull will be consistent and will have a driver who can do more than seize the opportunity.
If Mercedes leaves Valteri Botas for another year, Esteban Ocon can break the connection with Mercedes. The possibility of appointing is low. But given that it is so highly valued, Red Bull is not against taking risks ...
Roman Grojan is a very strange choice, but the stock has risen since it turned out to persuade the team to return to an Australian car. In fact, we found that the old spec was faster than the upgrade spec. Grojan is very fast when it is doing well. What he needs is an opportunity in a team that provides machines that regularly stand on the podium like Lotus.
Is it possible that Red Bull will try Kevin Magnussen, Gronnan's Haas teammate? Magnussen has been transferred to Haas for renewal and is highly appreciated by the team. Magnussen is still 26 years old and has a lot of time to improve. Over the past few years, this year has shown impressive performance, especially in qualifying.
Finally, Fernando Alonso is not without an option. In the past, Red Bull has admitted having negotiated several times with Alonso. The latest rumors report that they offered to Alonso as the first choice to replace Pierre Guthrie but were refused. Alonso has professed that he will return to Formula 1 if he is a team that can aim for the champion, and that may not be impossible if the current Red Bull Honda is competitive.
There is a shortage of Red Bull reserve drivers, and the option of appointing a former driver is very unlikely. If you have to choose the latter, you won't accept it, but there may actually be signs of hope. But there is no doubt that Red Bull hopes that Option 1, Arbon, will work.
