Speaking to Arsenal Player, Coquelin said: "He will be a big miss because we talk a lot off the pitch as well. I've dropped him a few texts to wish him good luck at Bournemouth.
"It's going to be a great thing for him to be able to play a full season, staying injury-free.
"We all know his talent, it's just a case of him staying injury-free. I know he had a strong pre-season so he will be all right. He's going to show the whole Premier League what he can do so he can come back even stronger.
"He will be focusing on having a great season at Bournemouth. It was a tough decision for him because he had a few options, but if he's decided to go to Bournemouth it's because he's 200 per cent committed.
"He's really ready and hopefully for us it will be amazing if he can come back fresh, fit and, even better, with a full season behind him."
