The 42-year-old insists there is no chance he will have divided loyalties when he comes up against his old employers on Thursday
Sevilla head coach Unai Emery says Valencia are firmly in his past as he prepares to face his former club in the first leg of their Europa League semi-final.
Emery will host his old employers on Thursday after seeing off Porto in the quarter-finals, with the return leg taking place next week.
The 42-year-old is anticipating a closely-fought contest against the fellow La Liga side, but insists there is no chance he will have divided loyalites on the night.
"I am 100 per cent Sevilla," he said.
"In all the teams I've managed I have good memories and Valencia have made me a better coach and a better person, but now my feeling is 100 per cent of Sevilla, and my only thought is to do good for all of us.
"There is only one match, we have to flow into that game. We don't think about the two legs, we are focused only on this 90 minutes.
"But in 90 minutes nothing will be solved entirely."
Emery coached Valencia between 2008 and 2012 and is yet to get the better of them this term, with a loss and a draw in the two games between the sides.
