The 23-year-old made a switch to the Emirates Stadium earlier on this month when his contract at German outfit FC Schalke expired.
German-born Kolasinac, who represents Bosnia-Herzegovina on the international stage, can play at left-back, the left-hand side of attack and at times in a centre-back position.
The versatile player will now join a team that recently finished outside of the top four in the Premier League, but lifted the FA Cup by beating the English champions Chelsea at Wembley.
Wenger, who has been at the club since 1996, offered his thoughts on the club’s new addition and what he can bring to the table in north London.
“He’s very compact as a player, very strong and determined in the challenges,” Wenger told the Arsenal player. “He’s good in the air as well, so overall I believe he has all the attributes to adapt to English football.
“What he will give us is the fact that he’s a player who can give assists, who can go forward, who can contribute good crosses.
“So overall, I think [Kolasinac] can contribute a lot to help us to be more dangerous going forward.”
During the recently concluded season, Kolasinac played 36 matches in all competitions for a Schalke team that finished tenth in the Bundesliga.
Over the course of the campaign, Arsenal’s new signing played as a left-back, left-sided midfielder, centre-back and defensive midfielder.
The majority of those encounters came at full-back or on the wing as he found the back of the net on three occasions added with his nine assists.
Kolasinac will now move to the Emirates where he will challenge the likes of Nacho Monreal and Kieran Gibbs for a first-team spot.
