The 23-year-old has been outstanding despite being unfamiliar to English football.
There is a tempo and physicality to England's top flight which can require an adjustment period, but Elneny has adapted seamlessly to both aspects. In truth, he simply does not look like a player with three months of English football under his belt.
With that being said, Elneny has suggested that Arsenal fans haven't seen anything yet, suggesting that he is not yet at the peak of his powers.
"I’ve improved my mentality and did what I could, hopefully the best is yet to come," he told the club's official website.
With Santi Cazorla back to full fitness, it will be interesting to see how manager Arsene Wenger uses both players in the same first XI - if indeed he does.
Elneny has been playing Cazorla's central midfield role, but the diminutive Spaniard is easily one of the Gunners' most influential players and keeping his spot will be difficult.
The Arsenal new boy has, however, shown an aptitude for the physical side, meaning he might well rival Francis Coquelin for the anchor role next term.
