Borussia Dortmund's Niko Kovac elated for Serhou Guirassy after ending goal drought
Borussia Dortmund head coach Niko Kovak has expressed his joy after striker Serhou Guirassy ended a seven-match goalless run in the Bundesliga against Bremen.

Leipzig suffered a humbling defeat in the opening match of the season, with Harry Kane scoring a second-half hat-trick, Michael Olise adding two, and Luis Diaz netting on his Bundesliga debut. Bayern remain unbeaten this season, recording historic results underlining their dominance in German football.
Speaking to the media on Thursday, Raum called Bayern "the best team in the world at the moment" but said Leipzig will offer a very different challenge this time.
"They killed us last time," Raum admitted. "But we have new players now, and we play completely differently to the start of the season. The coach has a better feeling for us, and we understand what he wants."
The 27-year-old, who captains Leipzig and is part of the Germany squad alongside several Bayern players, added that the previous defeat has fuelled their motivation.
"It was tough after the first game, especially as my first match as captain. Conceding six goals isn't nice," Raum said. "Of course, it's extra motivation. I know some of them well, and I hope this weekend they don't have their best day."
Leipzig returned to winning ways on Wednesday, beating Freiburg 2-0 to end a two-game losing streak, while Bayern have lost just once in 27 matches this season.
Elsewhere in the Bundesliga this weekend, second-placed Borussia Dortmund host St Pauli on Saturday, and fourth-placed Stuttgart welcome Union Berlin on Sunday.
