Soccer-Manchester United's Januzaj joins Dortmund on loan

* Belgium international joins for a season * Dortmund play in Europa League (Adds Januzaj quotes, details) BERLIN, Aug 31 (Reuters) - Borussia Dortmund have signed Manchester United winger Adnan Januzaj on loan for a season, the German club said on Monday. The 20-year-old Belgium international was reportedly a target for several European clubs including Tottenham Hotspur, Olympique Marseille and Valencia. "Adnan is a high quality and versatile player who complements our attack," Dortmund sports director Michael Zorc said. Januzaj made four appearances for United this season, scoring in the 1-0 win over Aston Villa this month. "Borussia Dortmund are a big club and the fans are supposed to be great here," Januzaj said in a statement. "I want to do big things with the club here." Januzaj will not have the chance to play in the Champions League because Dortmund have qualified for the Europa League after a disappointing last season. They are, however, top of the Bundesliga table after three straight wins, ahead of champions Bayern Munich on goal difference. Januzaj made his first-team debut for United in the 2013-14 season but has not earned a regular starting spot under coach Louis van Gaal. His contract with United runs to 2018.
