"If he wants to be part of the best project in football then there is only one club to sign for," the Sweden captain told The Sun.
"Only he knows the decision he is going to make in the summer but the project we are trying to build here is clear.
"We are not content with being the dominant force in France, we want to be the top club in Europe as well.
"I can understand why the owners are interested in Rooney — he is in the top 10 of strikers in Europe."
The 27-year-old's future remains up in the air after he was omitted from the club's starting line-up for their Champions League clash against Real Madrid last month.
