The Premier League side signed the Egypt international Mohamed Elneny in January. Elneny arrived from Basle for a £5million fee and he has thrived since arriving at the Gunners.
In an interview with the Evening Standard, Francis Coquelin said, "It's going well, he's a great addition to the squad. He's settled really quickly, because don't forget he's only been here for two months.
"I thought he was fantastic in the game against Barcelona, and against Everton as well.
"We are getting stronger each game, and if it can carry on this way it will be a good partnership. To be honest though, we have got lots of quality players in the middle, so any players that play in there can perform."
