What was said for you to join Arsenal?
He spent loan spells away at Lorient, Freiburg and Charlton before eventually becoming a first-team fixture in the second half of the 2014-15 season. Winning the FA Cup [in 2015] was special. Apart from the Swiss midfielder, Aaron Ramsey, Jack Wilshere and recently, youth-team product Joe Willock has also started in midfield ahead of Coquelin.

I owe a lot to Arsenal, it has been nine years of my life and I will never forget it. It is hard to leave.

Seemingly settling in well on the continent, Coquelin could make his home debut against Alaves in the Copa del Rey on Wednesday evening.
"I trust what he tells me", Coquelin explained while praising Arsenal's injured star Cazorla. After training, the coach told me about his great ambitions: to build a great European team.
"He (Cazorla) told me it's an excellent club which I will not regret joining". I am arriving with no particular status.
'I know Geoffrey Kondogbia and Dani Parejo are two high level players there. It is up to me to get to that level.
