While he is not going to force an exit, The Star states that he is likely to exit the club if a big enough offer arrives.
The Premier League's relegated side Sheffield United have been linked to his signature in recent weeks.
He's been massive since I've come in," Evans said of Johansson at The Star Football Awards, where he won the Millers' player of the season award.
But I've watched him on many occasions prior as well. He's top class on the pitch and he's top class off it too.
But we live in the real world and there are seven or eight big clubs in the Championship all looking at him. If he goes on that journey, we wish him every success.
We love him here. I've been fortunate to have (Emiliano) Martinez in goal before, and Johansson in goal. I've had two top goalkeepers and it'll be hard to replace someone of that quality."
