The Paraguayan joined Blackburn in the summer of 2007 from Bayern Munich, but has recently been linked with a move to both Manchester City and Manchester United.
“Roque is a fantastic player and there are always going to be rumours of him going to other clubs,” Emerton told Setanta Sports News.
“We would like to hold on to him as long as we can and I think as far as Roque is concerned, I think he is very happy at Blackburn at the moment and will stay with us for many years to come.”
