The Australian's future is uncertain after agreeing to terminate his McLaren contract at the end of the current campaign after two testing seasons with the Woking-based outfit.
The likely options for Ricciardo are a return to Alpine after a tumultuous end to that relationship in order to make his McLaren move, or a switch to Haas in place of Mick Schumacher.
Asked if he was bothered about who partners him next season, Magnussen replied: "It is hard to say it doesn't interest me but I know my role in that process is non-existent.
"All I can do is wait patiently to see who is going to be there. For myself, I hope that we will still have someone good in the car next year.
"The focus is we score points and move up as a team so we can grow long term."
"I don't know if he could make the team better" - Magnussen
Ricciardo was unable to make an impact at McLaren despite winning the Italian Grand Prix last season.
The 33-year-old has failed to hit the heights of his Red Bull days since leaving the Milton Keynes-based outfit for Renault.
Magnussen conceded: "I don't know if he could make the team better, I have never raced against him.
"From the outside, he has always been someone I thought was extremely good but it is just very hard to judge in reality - how much of that was him being in a good car and how much of that was actually him.
"He obviously went up against Max and did really well against Max and I am pretty convinced that Max is as good as he looks.
"Who knows? It is not my job to think about these things."
