The Egypt international has completed a drawn-out £5m (€6.6m) transfer from Basle “subject to the completion of regulatory processes” but he is expected to be registered in time to be involved at Stoke on Sunday.
And with the Gunners top of the Premier League, in the fourth round of the FA Cup and the last 16 of the Champions League there is plenty to play for.
The latter seems the toughest target to achieve with Arsene Wenger’s side drawn against defending champions Barcelona, but that has not stopped Elneny setting his sights high.
“I am hoping that we win the Premier League and cup this season, and the Champions League as well,” he said.
“Arsenal is one of the world’s greatest teams, and I am very keen to participate positively with my new team and to give my best for the team and for myself.
“Arsenal is one of those teams that everyone enjoys watching and of course I would love to play for such a great team. It is an indescribable feeling (to have signed).
“Mr Wenger is a highly-respected manager and one of the world’s best managers; it is my honour to be trained under his management.
“I would like to tell (the fans) that, although you have not seen much of me, I promise I will contribute positively with the team.” Wenger is convinced Elneny has the attributes to succeed in the Premier League.
“I believe he will be a good addition to the squad,” the Arsenal boss said.
“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 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.”
While the best Elneny could hope for is a place on the bench for Sunday’s trip to Stoke, in-form midfielder Aaron Ramsey is set for a key role.
The Wales international has scored in his last two matches, including his side’s opener in the entertaining 3-3 draw at Anfield on Wednesday, and he admits he is confident about his sharpness in and around the penalty area.
“I am feeling confident in there,” said Ramsey.
“I know my team-mates have the ability to pick my runs out and give that final ball for me to get on to it.
“It was a good ball from Joel (Campbell) again so I was delighted with that goal.” The game saw Olivier Giroud score twice, meaning he has found the net in the last 11 away matches, taking his tally to 18 for the season and 12 in the league.
“It shows character. Overall he is improving game-by-game and that is very positive,” Wenger said. “This team has quality and spirit. I could smell every time we went into the final third we could be dangerous.”
They will need all that attacking intent at the Britannia Stadium where they have not won in five visits, including three defeats. Ramsey added: “We have a tough game coming up against Stoke — we haven’t found it easy the last few times we have been there but we will be looking to get back to winning ways and get back on another run.”
