The Gunners are fairly familiar with this duo, as they faced off against them back in the club's 2011 tour of Japan. Both Yukari Kinga and Shinobu Ohno (pictured above on the right and left respectively) were on Japan's 2011 World Cup champion squad and their 2012 Silver Medal winning Olympic squad. Simply put, these two are world class players.
Let's start with Ohno. The forward was last on loan with Lyon, which is arguably the best women's club team in the world (although I'm sure Wolfsburg would have something to say about that), and while she didn't play all that much she was still training with some of the best players in the world. Internationally, Ohno has a bit longer of a resume.
In the 2011 World Cup Ohno scored one goal in group play against Mexico, and also tallied an assist, and was named to the tournament's All Star team. She started all six games for the team. At the Olympics Ohno also had a solid performance with one goal and two assists.
I'd expect Ohno to come in and immediately make an impact at the forward position considering the lack of depth Arsenal currently has at the position. I also wouldn't be surprised if she was in the starting eleven.
Switching over to Kinga, the defender comes over from INAC Kobe Leonessa, currently the best team in Japan's women's league the L League. Internationally, Kinga had an assist in the 2011 World Cup and she started every match. In fact, Kinga played every minute of every World Cup match Japan played en route to the title. At the Summer Olympics Kinga played on a defensive back four that had three consecutive clean sheets, tied for second most in Olympic history.
While the defensive situation for Arsenal seems to be a little crowded, there are absolutely no negatives to adding a world class defender like Kinga. Not sure if she will be a starter, but I wouldn't be surprised if she is.
All in all these two signings are probably two of Arsenal's best this offseason. Not to hate on Sio Chamberlain and Casey Stoney, but these two are internationally recognized as some of the best players in the world, and play for a Japan team that has been dominating the past three years.
I'm not sure if there are any more signings in store for the Gunners before the season starts this April, you can check out the schedule here, but this is an excellent step towards a top two league finish.
