He said: “I first heard of the interest through my agent and through some other players who spoke very highly of Arsenal to me.
“I was really happy and flattered when I heard about Arsenal’s interest. I was very hopeful to get the chance to come here.
“There was some contact when the transfer window opened.
“As always in football, clubs have to evaluate what they need, but they showed interest when they got in contact.
“Things happened more quickly towards the end of the window so it could be made official.”
