"It's going well, he's a great addition to the squad," said Coquelin. "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.
"We rotate in the middle so you have to be able to play with everyone, and combine well with them," he said. "We talk a lot as well of course. He's a new player so we are here to help him understand one another. We talk a lot on the pitch as well, and that is a big help.
"Of course he has natural qualities too and that makes everything easier as well. As soon as you play for Arsenal Football Club, you know you will be able to play alongside any player because they must have qualities to be here.
"You need to play together in training, in games, talk a lot, but at the end of the day you each know that the other player has the needed qualities."
