The 29-year-old fan favourite joined Bundesliga side Schalke in 2010 before moving to second-tier Union Berlin last summer. Uchida, who represented his country at the 2010 and 2014 World Cups and has won 74 caps, is set to join his new teammates next week as he looks to win a place in the national side for the FIFA World Cup 2018 in Russia this year.
