After 2-0 from a one-sided first game, the former Arsenal manager recalled that their opponents had lost just three of their 56 matches in a quadruple season. “I did not want to hear those details, but I did,” he said. “It’s a difficult task, but we are working on the game. “We have to play a perfect game. We have to find our excellence in certain things and maybe achieve something that no one else has achieved, which is this kind of return. “We will try to find some weaknesses, something that no one has done this season.” Liverpool completely dominated the midfield battle at Anfield last week with Thiago Alcantara in his best form since joining the club at the start of last season, the player of the match. Emery accepts that they can not allow this to happen again. “They played a terrible game at Liverpool,” he said of the Reds midfield. “Thiago was the player of the match, Fambino was fantastic in Liverpool. “They are two players who can play very good football, but they have the pace and intensity of work and they were world-class in Liverpool. [last week]. “If the player of the match is a Liverpool player again, we will definitely be out, but if he is ours, we can be there.” There has been some positive news for Emery with striker Gerard Moreno, who missed the first leg, back with an injury, although former Bournemouth winger Arnaut Danjuma, who has a leg injury, may be missing. “Gerard trained with the rest of the group today,” said Villarreal’s boss. “I do not know to what extent he will be suitable for a dispute. We will not take any risk. “
