Henry was asked about Coquelin on Sky Sports:
For me the best thing [Arsenal have] done [this season] is bring Coquelin back from Charlton. Maybe if he hadn’t come back and played the way he did recently, Arsene would have gone and bought a defensive midfielder.
On what Coquelin brings to the side:
He has been amazing, Arsenal don’t look like they will concede, they can score and he gave everyone protection everybody was talking about. Sometimes you look for that player and they are right in front of you. But the guy has matured, he went on loan, and knows he had to perform and he is doing it.
On how Coquelin saved Wenger's January window:
What Coquelin does is allow you to go for the player you want in the summer, because in January you go for the player that is available. Coquelin allowed Arsene to go for someone he really wants, or if Coquelin does the job really well, he can stay.
On Arsenal's title chances:
If [Arsenal] go on a big run, you never know what is going to happen. Everyone is raving about Sanchez, and rightly so because he is amazing. But the key for me was putting Cazorla in the middle of the park.
