BERLIN: Borussia Dortmund have been urged to rediscover their killer instinct, and silence lingering doubts about a lack of ruthlessness, in order to stay in the Bundesliga title race this weekend.
Back-to-back draws against mid-table teams Eintracht Frankfurt and Werder Bremen -- having been ahead on both occasions -- left Dortmund eighth in the table.
They are just three points behind leaders Bayern Munich in a tightly-packed top half, with five teams just a point behind the defending champions.
Bayern host mid-table Hoffenheim on Saturday hunting a fifth straight win, boosted by Tuesday's stunning 7-2 away romp at Tottenham Hotspur in the Champions League.
Dortmund need a win at third-placed Freiburg on Saturday to stay in touch.
Having won 2-0 at Slavia Prague on Wednesday in the Champions League, a second victory in four days would put Dortmund's Bundesliga campaign back on track.
Goalkeeper Roman Burki has said the team must 'man up' and get ruthless in Freiburg, a notoriously hard place to pick up three points.
With Mats Hummels restored to the team after a back injury, Dortmund's defence should be tighter at Freiburg.
Reus reacted angrily when a Sky reporter recently asked if the team had a mentality problem and midfielder Axel Witsel batted off a similar question after the Bremen draw.
"Oh man, don't ask me that -- mentality isn't the problem," insisted the Belgium star, but doubts still linger.
Chief executive Hans-Joachim Watzke agreed with Burki that Dortmund must get ruthless, even at the expense of their attack-minded football, to grind out wins.
"I believe that we must stop being in love with our own football - instead, we should be in love with winning," Watzke told Munich-based daily Sueddeutsche Zeitung.
"That's what it's all about."
Watzke says Dortmund's ultimate goal must be to end Bayern's run of seven straight league titles, "we're trying everything".
In order to usurp the Bavarians, Dortmund must mimic the relentless ruthlessness of Juventus, who have been Italian champions 35 times, says Watzke.
"We should learn to defend our goal again with teeth and claws," he said.
"They (Juventus) are extremely focused on the result.
"We need a bit more of that, so we don't just define ourselves through beautiful football, but also through tough defensive individual work."
