It remains to be seen what kind of impact the new boys can have, as Arsenal prepare for a testing opening to the new season against Manchester City and Chelsea, but the Gunners are setting the loftiest of targets.
Ahead of their first showdown on English soil, Emery has welcomed the challenge of getting one over on his compatriot.
"Today, we had a meeting with the players to close all the possibilities to leave or come with more players", Emery said.
"In my career, I want leaders in the team. If we play good and are consistent like last season, we have a chance to repeat [our title win]".
Arsenal have won just two of their last 12 encounters with Man City in all competitions.
And the former Paris Saint-Germain and Sevilla coach has stressed the importance of Arsenal being on the front foot. "I have confidence in myself, and also I can give them the confidence".
"The same when we are thinking defensively, I want our strikers to be thinking: 'We need to protect the goalkeepers.' I want those two moments to feel the same for all players".
The Colombian worldwide will also likely leave the club as Unai Emery says because he has played as a back up for Petr Cech for the last three years and the gunners signing Bernd Leno clearly showed that the gunners don't have trust in him anymore.
"Each player has this quality, this characteristic to help the team as a collective". But then also we need to build [a mentality] and it isn't a thing you find quickly. "But for me, I want to enjoy the way [we do it]".
