The Spanish coach has been charged with guiding Arsenal back into the Champions League qualification spots after they finished in sixth place and without a trophy last term under Arsene Wenger.
Arsenal have not qualified for the Champions League for the last two years and look to be facing more competition than ever to break back into Europe’s elite club competition.
The north London side have made a solid start to life under their new manager and they are unbeaten in 10 Premier League games after losing their opening matches of the season against Chelsea FC and Manchester City.
The Gunners will take on Bournemouth on Sunday lunchtime as they look to bounce back from three straight draws in the Premier League.
And Emery has warned his players that they will need to step their games up if they want to seal a top-four finish this season.
Speaking at his pre-match news conference at London Colney on Friday, Emery said: “If we want to be in the top four, we need to improve things. We are improving things. The performances at the moment are not bad.
“But Sunday is another test. A big test. They are behind us. We need to win to be closer to the top four. We need more.
“We have the capacity to score with different players and this is very important for me. But in the balance we also need to be better in defensive moments.
“It is not easy. We are working and speaking to do more. We need more. We need to get better.”
Arsenal have not won the Premier League title since their famous unbeaten triumph in the 2003-04 campaign.
