We were not controlling the game and they could have taken one transition and scored one goal and I was literally worried.“The most important thing now is to build a team and to build a structure tactically with our idea, our identity and then try to get confidence in the players through it.“Some players I am watching. Sometimes we are playing individually. We need to adapt in our style how we want to play and through it we were taking experiences here being successful and again, of course, this is the way I want.“It’s one point keep going. Now we are starting (in) Europe on Thursday. We are going to play at home two matches now and hopefully we can feel better at home.“And of course we have to react in the Premier League because it’s the first competition where we have to try to to achieve our objective and should be through how we create and how we want to to build a team with our identity.”GettyEmery has called for his players to ‘react’ ahead of the start of their Europa League campaign[/caption]Villa remain winless with the draw leaving Emery’s side 18th in the table on three points from five matches.They follow up their clash with Bologna by hosting Fulham three days later on September 28.
