Chelsea held out with 10 men for the entire second half to frustrate Liverpool as the first heavyweight clash of the Premier League season between two title contenders ended 1-1 at Anfield on Saturday.

Kai Havertz's looping header put the visitors in front before Reece James was sent-off in first-half stoppage time for handball on his own goal line, and Mohamed Salah converted the resulting penalty.

But Jurgen Klopp's men failed to make their man advantage count in the second half as the European champions showed resilience to dig out a precious point that strengthened their title credentials.

With Cristiano Ronaldo back at Old Trafford, both sides and Manchester United are expected to give Manchester City a much tougher challenge to retain the Premier League title this season.

In Germany, Robert Lewandowski scored a hat-trick as Bayern Munich thumped Hertha Berlin 5-0, with the Poland striker passing the milestone of 300 goals for the defending Bundesliga champions.

Bayern took an early lead through Thomas Mueller before Lewandowski struck either side of a Jamal Musiala goal.

Having scored a record 41 goals last season in the Bundesliga, Lewandowski has already netted five times in three league matches this term.

The rout saw Bayern move into second in the table, level on seven points but behind early leaders Bayer Leverkusen, who swept Augsburg aside 4-1 thanks to two early own goals, on goal difference.
