ANKARA (AA) - Borussia Dortmund topped the German Bundesliga standings after a 6-1 win over Cologne in a Saturday league match.
Dortmund duo Sebastien Haller and Marco Reus scored double each to help their team smash the visitors at the Signal Iduna Park.
The home team led the first half 4-1 after Cologne's Davie Selke netted.
Raphael Guerreiro, who scored the opener in the 15th minute, and Donyell Malen, another Dortmund player to have tallied a goal in the first half, were the other scorers for the winners.
Reus surpassed Dortmund legend Michael Zorc by scoring 161 goals for the club in all competitions, which means the 33-year-old midfielder is now Dortmund's second-highest goal scorer of all-time.
Former midfielder Zorc, 60, had 159 goals for Dortmund between 1981 and 1998.
Reus, a Dortmund regular since 2012, needs to score 17 goals to beat Dortmund's all-time highest scoring player Adi Preissler, who died in 2003.
Leaders Borussia Dortmund have 53 points in 25 matches, and are in a tight battle against defending champions Bayern Munich.
Second-placed Bayern Munich have 52 points before their visit to Bayer Leverkusen on Sunday.
RB Leipzig, Union Berlin and Freiburg have 45 points to chase Bayern Munich.
