The Midlands club sit in the Champions League qualification spots but the coach thinks that there is more to come from his side as they prepare to take on Newcastle in a league fixture on Tuesday (30.01.24).
Emery said: "We have to be consistent in our mentality and it is a process.
"We are building a team and we are still working a lot of things to improve and we have to feel strong in our structure and feel in our commitment strong and everybody ready to play and help, be demanding too.
"The results, scoring goals and conceding less goals, we have to try in the second part of the season to take on a great challenge for us and I am excited. I am excited being demanding and knowing it will be very difficult and this is a message to the supporters, to the players and for everybody."
Villa were thrashed 5-1 by the Magpies when the two sides met on the opening weekend of the season last August but Emery expects things to be completely different this time around.
He said: "It was tough, it was tough in the match. We can remember that it was the moment which Tyrone Mings had his injury and that was a difficult moment.
"We were with some circumstances, really bad. But we analysed and worked after that match trying to analyse so we can improve and I think now, it is completely different.
“We lost there but it is completely different and we are ready."
