The 23-year-old Egyptian midfielder joined the Gunners on Thursday from Swiss club FC Basel for an undisclosed fee believed to be in the region of £5million.
When assessing the arrival of Elneny, Gunners boss Wenger felt that his three years spent in Switzerland competing in the Swiss Super League, Champions League and Europa League will have him well-prepared for the rigours of the Premier League and additional competitions.
"Overall I believe he will be a good addition to the squad," the boss told Arsenal Player.
"First he has not come in straight to a big club, he had an intermediate stay in Europe so the adaptation is less of a question mark.
"He is 23 years old and has already got Champions League, Europa League and Swiss League experience. He is a player who is adaptable in midfield.
"He can be box to box and be a holding midfielder so that is for us very promising. We wanted a versatile player and I wanted a player who can play defensive but can as well play to box to box.
"His strengths are his technical level, his vision, his intelligence, his disciplined attitude and his physical attitude to compete at a high level. I think he has the physical qualities to play at the top level.
"Where he needs to adapt is to the challenges, the force needed in the Premier League to survive. I think that could demand a little bit of adaptation. But overall I think he has all the attributes to do well."
