Two goals from Marcos Alonso gave Chelsea a 2-1 victory over Tottenham Hotspur on Sunday in the first-ever Premier League game at Wembley Stadium.
For all the noise and wall of flags that greeted their arrival, Spurs, who are playing at Wembley while their new stadium is constructed, needed an early goal to feel at ease in their surroundings.
It was Chelsea, however, who made the breakthrough against the run of play on 23 minutes when Alonso thumped home a superb free kick from 20 metres after Dele Alli had fouled David Luiz.
The shock jolted Spurs, who spent much of the game peppering Chelsea's goal with Harry Kane hitting the post and Christian Eriksen also going close.
They eventually scored when Michy Batshuayi put through his own net from Eriksen's free kick two minutes after coming on but, as Spurs pushed for the winner, Alonso hit back on 88 minutes with a shot that went straight through keeper Hugo Lloris.
At Huddersfield, the Terriers made it two wins out of two at the start of its first Premier League season by beating Newcastle 1-0 on Sunday, condemning its fellow promoted team to a second successive loss.
Australia midfielder Aaron Mooy scored in the 50th minute, curling in a shot from 18 yards following a one-two with Elias Kachunga to secure the victory for David Wagner's team.
"The boss has a saying to have no limits and we all stand behind that," Mooy told British broadcaster Sky Sports. "It has been a great start so far, but we can't get carried away, it's early in the season. We just have to keep working hard and keep trying to improve."
It was Huddersfield's first top-flight game at home since 1972 - 20 years before the formation of the Premier League. Huddersfield opened the season by beating Crystal Palace 3-0 last weekend, while Newcastle lost 2-0 to Tottenham in the first round.
"People wrote us off last week at Palace but we couldn't rest on our laurels and we have made a statement," forward Tom Ince said. "The manager has come and said it, we are not here just to be part of the league, we are here to show people what we are about and that we deserve to be in the Premier League.
"Today was about winning. Two games, six points and we move on."
