The Rovers chief saw a reported £4million offer for the free-scoring marksman rejected earlier this week.
"As every bid goes, it's considered, it's not considered or it's thrown out," he told Sky Sports.
"I think it's just a process which, obviously, the selling club, if they do want to sell, and quite often they don't, then they can politely tell you your interest is not welcome.
"I don't know what will happen now; I will leave that in the hands of the directors and see how that develops."
Kean, however, is in no doubt of Rhodes' ability: "I think he's a quality player. If you are a natural goalscorer you can score all types of goals. Left foot, right-foot, headers, volleys - and he can certainly do that.
"But like I said, we will be respectful of the club he's playing at this moment and if we can get permission to speak to him, if the bid is accepted then great, if not we'll have to move on."
