Unai Emery says World Cup winner Emiliano Martinez is "100%" focused on Aston Villa ahead of his anticipated return to the side for Wednesday's home fixture with Wolves.Martinez returned to club duty on Sunday but was only named on the bench for Villa's 2-0 victory at Tottenham with Swedish goalkeeper Robin Olsen deputising and keeping a clean sheet.Emery revealed it was always his intention to give Martinez extra time out of the starting XI, but hinted the 30-year-old, who courted controversy for his post-World Cup final celebrations, was set to be back between the posts for the local derby."Emiliano had a very good start with us [on Sunday], being in the squad and travelling with us," Emery said."He had training two days, Friday and Saturday, and now more sessions so I think he will be ready after his rest and after the emotion he had with winning this World Cup."I think for us he is very important and we can be proud of him for being a winner at the World Cup but now his focus is 100% with Aston Villa."Villa's impressive performance and result in the capital made it three wins out of four since Emery was appointed in November.It has eased their relegation concerns but the Spaniard will be determined to build on their latest away win by turning Villa Park into a fortress again.The visit of Wolves marks the first of three consecutive home fixtures and Emery will face a familiar opponent in the dugout with Julen Lopetegui swapping La Liga for the Premier League like his compatriot.Emery added: "Julen is a very, very good coach."He has experience and he decided as well to come to the Premier League and I think he is a fantastic coach."To play against teams he managed and coached is a big challenge because he demands a lot
