Valencia coach Unai Emery says they won't be underestimating Chelsea striker Fernando Torres tonight.

Torres is expected to start after the latest turbulent week of his topsy-turvy Stamford Bridge career.

"We have to be extremely careful with him," said Emery, who shrugged off the prospect of the returning Juan Mata coming back to haunt his side barely a month after joining Chelsea for £23.5million.

"I'm not really going to be thinking about Mata because Chelsea have a lot of important players.

"We're really capable of winning this game and we hope we enjoy it.

"I'm not going to be especially concerned about Mata."
