Despite the Brazilian enjoying a productive campaign at the Allianz Arena, Bayern will not be signing the playmaker on a permanent basis.
However, while acknowledging Bayern's stance regarding a full-time transfer, Rummenigge has left the door open for Coutinho to return next season.
Speaking to Der Speigel, Rummenigge said: "The option expired and we haven't activated it.
"We're going to plan our squad for next season and we'll see if he still has a role to play with us or not."
Barcelona would prefer to cash in on the 27-year-old, who has contributed nine goals and eight assists in Germany's top flight and the Champions League this season. body check tags ::
