Chelsea winger Gael Kakuta is unsure about a long-term stay with Rayo Vallecano.
Kakuta has been impressive on-loan at Rayo this season.
"I don't know. At the moment, I am a Rayo player, later we'll see," said the Frenchman.
"Here, the football is more technical and tactical. That suits me. I am playing regularly and I'm happy with how it's going. I get to express myself out on the pitch so it's nice for me. I like the Spanish league."
