Barcelona, PSG & Bayern keep up perfect starts

Kylian Mbappe failed to score in his first three La Liga appearances but has now scored three goals in his last two games

The giants of the European leagues continued to flex their muscles this weekend as Barcelona, Bayern Munich and Paris St-Germain maintained their 100% records.

Teenager Lamine Yamal shone for Barca with two goals in their 4-1 win at Girona while Harry Kane hit his fifth hat-trick in a Bayern shirt as they thrashed Bundesliga new boys Holstein Kiel.

There were goals for Tammy Abraham and Conor Gallagher too.

Here's what you may have missed across Europe this weekend.

Mbappe finds his feet as Barca lead the way

Dani Olmo is the fifth player to score in his first three La Liga matches for Barcelona after Hristo Stoichkov (1990), Dani (1999), Zlatan Ibrahimovic (2009) and Cesc Fabregas (2011)

Barcelona stayed top of the standings in Spain as Yamal scored twice in a dominant first half.

Dani Olmo and Pedri also found the net before former Manchester City winger Ferran Torres, who had only been on the pitch for 17 minutes, was shown a red card for a heavy challenge on Yaser Asprilla.

Real Madrid are four points behind after a 2-0 win at Real Sociedad secured with second-half penalties by Vinicius Jr and Kylian Mbappe.

Real boss Carlo Ancelotti said his side were not dominant enough to deserve the win despite being without midfielders Jude Bellingham, Eduardo Camavinga, Dani Ceballos and Aurelien Tchouameni.

"It was a complicated match. We didn't deserve to win, because Real Sociedad pushed us really hard," he said.

"We held on and suffered, showed character and a lot of commitment. I value that a lot because it's not easy to find commitment in a team with so much talent and quality and we did it."

England midfielder Conor Gallagher and former Manchester City forward Julian Alvarez scored their first goals for Atletico Madrid as they beat Valencia 3-0.

'Nasty' Fabregas' wait goes on as Napoli go top

Cesc Fabregas is yet to win a game as permanent Como boss

Romelu Lukaku made two and scored another as Napoli went top of Serie A with an impressive 4-0 win at Cagliari.

Premier League exports Scott McTominay and Billy Gilmour both came on as late substitutes for their debuts as Antonio Conte's side made it three wins from four.

Former Arsenal and Barcelona midfielder Cesc Fabregas was left frustrated after seeing a first Serie A win as head coach slip through his fingers.

Como, newly promoted to Serie A this season, squandered a two-goal lead to settle for a 2-2 draw with Bologna on Saturday.

An early own-goal by Nicolo Casale and a second-half finish by Patrick Cutrone from the edge of the box put them in control but late strikes by Santiago Castro and Samuel Iling-Junior rescued visitors Bologna.

"We had an important chance to win, we were solid but we have to be better at closing it out," Fabregas said.

"I have to do more to help the boys be more nasty in front of goal and close out the game."

Unbeaten Juventus were held to a 0-0 draw at Empoli but new AC Milan coach Paulo Fonseca got his first Serie A win in style as four goals before the half-hour mark saw them thrash Venezia 4-0.

Two quick penalties from former Chelsea duo Christian Pulisic and Tammy Abraham sealed the win.

Champions Inter missed the chance to go top, drawing 1-1 with Monza.

Kane streak continues as Bayern cruise

Bayern Munich went top of the Bundesliga with a 6-1 demolition of Holstein Kiel on Saturday as Kane - who scored twice for England last week - bagged a hat-trick against the newly-promoted side.

Bayern's hold on the Bundesliga was broken last season with Bayer Leverkusen winning the title in a record-breaking undefeated run.

"I have said that this is just three games. I know, I know, for Bayern it is always important (to be in the top spot) but it is three games at the moment," coach Vincent Kompany said.

"If we continue as we do now, maybe at the end of the season - I don't even want to say it... We just have to keep going."

Champions Leverkusen bounced back from defeat by RB Leipzig a fortnight ago with a commanding 4-1 victory at Hoffenheim.

Dembele at the double

Ousmane Dembele has three goals in three starts in the league this season

Ousmane Dembele scored twice as Paris St-Germain came from a goal behind to beat Brest 3-1 and continue their perfect start to the Ligue 1 season.

Brest took a shock lead against the champions when Romain del Castillo converted from the penalty spot after Nuno Mendes fouled Ludovic Ajorque in the area.

But Dembele, who tormented Brest throughout on the right wing, ensured the teams were level going into the break by nodding home Marco Asensio's cross.

Two goals in two minutes in the second half then proved the difference for PSG, with Fabian Ruiz putting the hosts ahead with a superb strike from distance which he rifled into the top corner.

Dembele then doubled their advantage a minute later, following up after Randal Kolo Muani had an effort blocked.
