Borussia Dortmund’s prolific teenage striker Erling Haaland will miss their next Bundesliga match at Paderborn while Mo Dahoud has been ruled out for the rest of the season just as he was finding his form, coach Lucien Favre said on Friday.

Haaland, who has scored 10 goals in 11 Bundesliga appearances since his move from Salzburg in January, has a knee problem while Dahoud has an “unspecified knee injury”, Favre said ahead of Sunday’s game away to the Bundesliga’s bottom-placed side.

Second-placed Dortmund have dropped seven points behind leaders Bayern Munich after their 1-0 home defeat against the Bavarians on Tuesday.

Dahoud has started all three games since the Bundesliga resumed and had appeared to be gaining in confidence. “Each player needs confidence and Mo played better in Wolfsburg and better against Bayern... It’s a question of match practice and confidence,” said Favre.

With Dortmund not in action until Sunday, Bayern will look to extending their lead at the top to 10 points when they take on Fortuna Dusseldorf on Saturday.

Coach Hansi Flick is backing talismanic striker Robert Lewandowski to finally hit the target against Fortuna after years of trying.

The striker has scored over 40 goals for a fifth successive season but has never netted in the Bundesliga against Fortuna in five outings, thrice with Bayern and twice with previous club Borussia Dortmund.

“It is important to us that we stand up well and create chances. Then if we win and he scores, it would be all the better,” Flick said.

Third-placed RB Leipzig will continue their pursuit of their best ever Bundesliga points tally when they travel to Cologne on Monday.

Leipzig, who have 55 points from 28 games, are 12 points away from their best ever points tally of 67 which they achieved in their debut top-flight season in 2016-17.
