Barcelona announced at 5pm on Wednesday that Suarez would join Arsenal on loan until the end of the season, with the Gunners negotiating an option to make the move permanent in the summer.
"He played at Manchester City when he was a young player".
When asked what Suarez's best position is, Emery replied: "He can play on the right or left, or inside like a number 10".
The Gunners ace has struggled with knee and back injuries but head coach Unai Emery did not play him when fit either citing "tactical reasons".
Together, they won the Europa League in 2014-15 and Emery has always been a keen admirer of his qualities.
Having grown up in England, where he enjoyed his youth playing days at Manchester City, the native of Salceda de Caselas is more than familiar with his new club.
In the announcement Barca stated Suarez would spend the rest of the season on loan in the Premier League, while also revealing he had penned a contract extension until 2021.
He said: "One thing no one knows about me is that when I was little and I used to watch the Premier League on the TV, Arsenal were a team that really inspired me". "I used to watch Bergkamp and Henry - they're both legends of the club and hopefully we can follow in their footsteps".
"He did not play for Barcelona's first team a lot of times but he helped there and played in the Champions League".
With five years' experience at Barcelona, Suarez arrives at the club with a reputation for being a technically gifted player but he unlikely to give Arsenal the kind of midfield strength they look to be lacking.
Denis Suarez hasn't been at Arsenal long but already it seems as though he's making a strong impression on his new teammates. We have four captains, I don't know if you have come to my press conferences but I am going to repeat it but I think the others know it all.
