Sterling was gotten on Loan from Chelsea. The term was that if Arsenal loves his performance by summer, they will buy him but with the way things is i don't think Arsenal will want Sterling. He will be returned to Chelsea not minding the fact that he loves to play at Arsenal.
For the players who might be on the list for Arsenal to sell to raise fund i am suspecting Trossard (He also said he might want to leave the club), Jorginho; One of Arsenals best defensive midfielder but he has aged a little so Arsenal will be willing to let him go. Another player is Tierney, Thomas Partey and Fabio Vierra who was sent on loan to another club.
However, the Arsenal board will be blame if Arsenal don't win a title next season. I expect that aside from selling players to raise fund the club owners should give Arsenal enough funds to get players who will help win trophy.
I was one of the persons who was happy with the Raheem Sterling deal, a move at the last minute said to be a backup plan for Bukayo Saka which unfortunately hasn’t gone as expected. Raheem Sterling has obviously performed below expectations, there is a huge doubt that he will be signed at the end of the season. I think Arsenal will look at other options instead to strengthen their squad in the summer.
Raheem Sterling is not an option that Arsenal will want to keep beyond the summer. he couldn't even play well for Chelsea with a lot of armature players and has yet to make an impact since he joined Arsenal. from the look of things, he might just be approaching the end of his active football career if things continue this way because not a good coach in his right sense of reasoning will want to work with him considering how he has shown to be a lazy footballer that has almost lost the drive to play well. With Bukayo Saka's injury, he normally would have been a better replacement but we can all see that he is still found wanting in that regard. if he returns back to Chelsea, he will struggle to get a place back because the club has already worked on playing without him. the option will just be to look for a solution to his exit from the club which likely will mean that he is not just exiting both Chelsea and Arsenal, he might invariably be taken out of the premier league.
