A Harry Kane penalty and a second-half goal by Thomas Mueller was enough to give Bayern Munich all three points in the Bundesliga as they beat Freiburg 2-0 on Sunday and new head coach Vincent Kompany continued his winning start.

Bayern were awarded a penalty for a handball following a VAR review when Kane's header hit the arm of Freiburg captain Christian Gunter.

Kane stepped up to take the penalty himself, and the England striker sent Freiburg goalkeeper Florian Muller the wrong way, slotting the ball into the bottom left corner to give the hosts the lead in the 38th minute.

It was Kane's first goal of the new Bundesliga season, having topped the scoring charts of the German league last campaign with 36 goals.

There was little to separate the two side's in a cautious opening spell at the Allianz Arena but once Bayern got going it quickly turned into a fairly one-sided contest.

Jamal Musiala showed flashes of brilliance and new signing Michael Olise looked lively, but the duo failed to convert their chances.

The second half was a much quieter affair until Serge Gnabry's cross found Mueller, who beautifully controlled the ball and smashed it past the goalkeeper.

The 34-year-old Mueller made history for Bayern, making a club record of 710 appearances for the Bavarians. It was also his 150th goal in the Bundesliga.

"A brutally beautiful goal! I told the fans on the fence after the game that they should work hard this year because they need a few days off. We've got big plans this year," Mueller said.

Lack of precision

Juventus players should have been more precise in their attack as they played out a goalless home draw against AS Roma in Serie A on Sunday, coach Thiago Motta said.

Juventus dropped the first points of their league campaign after kicking off the season with impressive back-to-back 3-0 victories against Como and Hellas Verona.

"I think it's a fair result, in a balanced match. We didn't concede and we have one more point in the standings," Motta told a press conference.

"I'm very satisfied with the group and their commitment. We could have done much better today in precision in the offensive phase, but the opposing team knew how to defend and not give spaces."
