Juan Mata insists he would have no problem staying with Valencia.

Chelsea are chasing the Los Che midfielder.

"Moving can certainly be a positive experience but the truth is [I] do not know when [I will]. I have not raised the issue," he told AS.

"The day I left Madrid for Valencia was very important, with that fear in you [that] things may not go well. I have grown a lot as a player here and, frankly, I think I can keep growing."
