Emerys priority is to qualify for next seasons Champions League and one of his first tasks was to make Arsenal more resolute defensively after they conceded 51 league goals last season.
There is still work to be done with Arsenals defensive record the worst of the current top five clubs but Holding is confident that improvements are being made.
“The main difference is how were defending when were attacking,” he said. “When were up the other end of the pitch, how we are organised and prepared for a counter. That has been the biggest difference.
“Were really focusing on video work, moving as little as five yards in some positions which makes all the difference when getting to the ball. When we were playing we would be stood there and no one would be talking to each other, whereas now there is much more communication.
“We seem a bit more organised and a bit more together at the back.”
Club captain Laurent Koscielny has been absent for the entire season due to an Achilles injury which has given Holding the chance to stake a first-team place.
Although summer signing Sokratis Papastathopolous and Shkodran Mustafi began the season as Emerys first-choice defensive pairing, Holding has started Arsenals last six league games.
Holding was in and out of the Arsenal team under Wenger following his £2m arrival from Bolton Wanderers in 2016 and he admitted that this season has been his best for the club.
“I think this is my best run in an Arsenal shirt. Consistency-wise, its been 12 games consistently playing to a good level, not playing because someone is injured but on merit. That gives you more confidence.”
Arsenal toiled to a 1-1 draw against Wolves at the Emirates prior to the international break and will be looking to return to winning ways when they face Bournemouth at the Vitality Stadium on Sunday.
