Arsene Wenger believes Arsenal signing Lucas Perez possesses a bit of a surprise element.

The 27-year-old Spanish striker completed his £17million move from Deportivo La Coruña on Tuesday and according to Wenger, has all the abilities in his locker to quickly become a key player for the Gunners.

"I'm happy because I believe he has the qualities to integrate into our team very well," Wenger told Arsenal Player.

"I think people will be a little bit surprised maybe, because nobody knows him very well. He has travelled a bit across Europe.

"He's a late developer in this position because he has always played on the flanks. He's got a good eye for goal and had an outstanding season last year in a team that didn't create too many chances.

"I'm confident. He has pace, good technical levels, is a good finisher and he has the ingredients to be a success. It's always a little bit of a gamble to come from one country to another, with different challenges, but I believe it was a gamble worth taking. I'm excited about that."

Perez arrives at the Emirates Stadium having starred for Deportivo with 19 goals in 39 appearances in all competitions last season.
