Borussia Dortmund’s winger Marco Reus has sustained another injury after returning to action just a month ago. The 28-year-old German may miss his club’s Bundesliga tie at Bayern Munich on Saturday. He had been on a good run of form, bagging three goals in five games but now faces an uphill task of being fit for the match, which could hand Munich the trophy for a sixth straight season. “That’s why I don’t think he will make it this weekend,” admitted Dortmund head coach Peter Stoeger, who is unbeaten in his 12 league games since taking charge in December. Reus, who missed the 2014 World Cup with torn ankle ligaments and Euro 2016 with a groin strain, is desperate to play at Russia 2018 in June. He was left out of Germany’s friendlies against Spain and Brazil, who play at Berlin’s Olympic Stadium on Tuesday, to focus on his club form. Third-placed Dortmund, who are 18 points behind leaders Bayern in the table, want a win at the Allianz Arena to spoil Bayern’s title party. Stoeger said Japan midfielder Shinji Kagawa is expected to miss the next two weeks with an ankle injury while Andriy Yarmolenko will miss the tie after his foot injury sidelined him until towards the end of the season.
