Fernandez has been linked with a potential move to either Real Madrid or Paris Saint-Germain but he still has more than six years on his contract in west London. And he insists that he is "happy" at Stamford Bridge.
He added: "On a personal level, I feel great, I'm happy. I felt I grew both athletically and personally, and as the years go by, I feel much better. It's a combination of things; feeling good off the field has an impact on the pitch."
Rosenior, meanwhile, insists he has no worries over reports of Fernandez's future, adding: "It means nothing to me. When you’re a world-class player, there’s always going to be speculation that you can’t control. He’s a Chelsea player. He’s very important to me. I think we’re going to have a really good, hopefully winning relationship in the short term and the long term."
