BERLIN — Borussia Dortmund has named Thomas Tuchel to succeed Juergen Klopp as its manager on a three-year-deal, the Bundesliga club said Sunday. Tuchel, who managed Mainz for five seasons between 2009 and 2014, will take up the post from July 1 after Klopp announced Wednesday that he would be ending his seven-year tenure at the club. “Eight-time German champion Borussia Dortmund has appointed Thomas Tuchel as its new head coach from 1 July 2015, with the 41-year-old putting pen to paper on a three-year contract,” Dortmund said on their website (www.bvb.de). Bundesliga champion in 2011 and 2012 Dortmund, who also finished runner-up in the 2013 Champions League, has struggled this season and sits eighth in the standings after a brief spell at the bottom. — Reuters
