Sevilla-owned midfielder Denis Suarez is delighted to be playing for Arsenal boss Unai Emery.
Suarez's move to Arsenal meant a reunion with Emery - having worked with the Spaniard while on loan from Barca in 2014.
And the 25-year-old has heaped the praise onto his boss for helping him turn into the footballer he has become.
"I think Unai made me a football player, when I joined Sevilla I was a prospect.
"I was coming off the back of a great season in the second division with Barca B. But it was a big step up to the elite level. he really helped me."
