He faces a Guardiola who is now fully into the swing of things at Manchester City and had an unparalleled domestic campaign past year where City racked up 100 points.
Friendships between team-mates can be a key facet when it comes to improving team morale and Goal understands that Emery's high-intensity training sessions have been welcomed by the Arsenal squad this summer.
The Gunners have a shortage of left-backs with both Nacho Monreal and Sead Kolasinac ruled out, meaning highly-rated midfielder Ainsley Maitland-Niles, who has done a good job filling in for the others, will be up against Riyad Mahrez or Raheem Sterling.

Left-back Benjamin Mendy could start his first league game since September 2017, when he suffered a cruciate ligament injury against Crystal Palace.
He has returned to training this week but it's unclear as to whether he'll start the match or be among the substitutes. However, with Laurent Koscielny out of action until Christmas, another tried and tested centre-half wouldn't go amiss. Fernandinho, Kevin De Bruyne and a Silva - either David or Bernardo - is a familiar trio for the away side.
