Cristiano Ronaldo enjoyed a sensational return to Manchester United as his debut double inspired a 4-1 win against Newcastle on Saturday.

Ronaldo's second debut for United was the headline act as the Premier League resumed after the international break and the Portugal superstar did not disappoint his adoring fans at Old Trafford.

The 36-year-old insists he did not make his £19.8 million ($27 million) move from Juventus last month for a "vacation."

Kalidou Koulibaly made sure that Juventus' miserable start to the season continued on Saturday with the late winner in a 2-1 triumph for Napoli that put them top of Serie A.

Senegal captain Koulibaly knocked home the winning strike from practically on the goal line with five minutes to go at the Stadio Diego Armando Maradona to maintain Napoli's 100 percent start and move them three points clear in first place.

Chelsea striker Romelu Lukaku scored at Stamford Bridge for the first time as his double and a goal from Mateo Kovacic sealed a 3-0 win against Aston Villa.

After scoring on his second Chelsea debut in the win at Arsenal in August, Lukaku made it three goals from three appearances with predatory strikes in the 15th and 90th minutes.

Lukaku, who previously played for Chelsea from 2011 to 2014, is back with the Blues following his club record £98 million move from Inter Milan in the close-season.

Crystal Palace ended 10-man Tottenham's perfect start to the Premier League season as Wilfried Zaha's penalty and a late double from Odsonne Edouard sealed a 3-0 win.

Nuno Espirito Santo's side had Japhet Tanganga sent off for two bookings in quick succession in the second half at Selhurst Park.

South Korea forward Hwang Hee-chan scored his first Premier League goal for Wolves in their 2-0 win at Watford.

Brighton won 1-0 at Brentford thanks to Leandro Trossard's 90th-minute strike, while West Ham striker Michail Antonio was sent off in their 0-0 draw at Southampton.
