Who is Arsenal's first summer signing Sead Kolasinac?

Arsenal have wrapped up their first transfer of the summer as they just announced the signing of former Schalke defender Sead Kolasinac. The Gunners have beaten the likes of Chelsea, Juventus and Manchester City to sign the highly rated 23-year-old Bosnia and Herzegovina international.

Kolasinac joins Arsenal on a free transfer after his contract with German club Schalke came to an end and while the length of his contract is not yet revealed, reports say that he has signed a deal worth £7.5 million a year.

The Bosnian is expected to be just one of many signings Arsene Wenger is expected to make over the summer as he hopes to build a squad strong enough to challenge for the Premier League title next season. The signing of the former Schalke man is definitely big news for Arsenal but what kind of player are the Gunners getting in Sead Kolasinac?

Kolasinac has definitely made a name for himself in the Bundesliga last season but the things didn't get off to the best possible start for him. He started the season by spending the first few games on the bench as Baba Rahman was selected ahead of him but he managed to surpass the Chelsea loanee and made that left-back position his own.

One of his biggest strengths is his tackling and his ability to win the ball whenever he slides in. His imposing frame makes it really difficult for attackers to get past him and despite that, he is surprisingly quick. One of the things Kolasinac was asked to work on was his attacking side of the game and he has done so.

Here is a look at some of Sead Kolasinac skills and tackles for Schalke. 

He scored three goals and assisted seven last season for Schalke and was one of their top attacking threats. The Big Bosnian can also operate as a centre back and as left wing back and having thrived in that position since Schalke switched to a 3-5-2 and he should get straight into the Arsenal starting 11.

Unlike Arsenal's current crop of full backs, Kolasinac actually is a defender who defends. Hector Bellerin, Nacho Monreal and Kieran Gibbs are mostly known for their abilities to get forward and involve themselves in attack but Kolasinac is excellent in one-on-one situations and often deals with attackers by simply overpowering them.

"Arsenal has a huge tradition and I followed the club as a young boy, in the days of Jens Lehmann and Thierry Henry. Arsenal has always been a club that is well recognised in Europe and I'm pleased to be here," Arsenal.com quoted Kolasinac as saying.

"I'm a player who will try to help the team as well as I can. My strengths are my mentality. I think left back is where I feel most comfortable. I can play as part of a three at the back too or further forward. I'm really flexible." 

With all the confusion surrounding how to pronounce his last name, Arsenal released a video where the Bosnian tell us how his last name is said.
