We present a summary of events in photos.

SPAIN

Lionel Messi scored yet another hat-trick and surpassed 400club goals as Barcelona came from behind to win the Catalan derby 5-1 against Espanyol in La Liga.

The Argentine, who holds the La Liga and Champions League scoring records, produced a familiar devastating performance to take his record to 402 goals for Barca in all competitions, including 28 in friendlies.

European champions Real extended their club record winning streak to 18 matches in all competitions, staying two points clear of Barca while champions Atletico Madrid are a further two behind after their 2-0 victory at Elche.

ENGLAND

The Premier League race was given a new complexion after Chelsea's unbeaten start to the season ended with a dramatic 2-1 defeat at Newcastle United on Saturday and led to champions Manchester City closing the gap at the top to just three points.

Papiss Cisse struck twice for Newcastle to stun Chelsea, who had been unbeaten for 23 matches in all competitions under Jose Mourinho, before City took full advantage of the slip with Yaya Toure's penalty earning a 1-0 home victory over Everton.

City's delight, though, was tempered by bad news regarding the league's top scorer Sergio Aguero, who was left close to tears after suffering knee ligament trouble -- another in a long list of injury setbacks -- which will keep him out of their Champions League group decider against Roma.

Arsenal's hopes of a third successive win were dashed by a 3-2 defeat at Stoke City, after trailing 3-0 at halftime, while West Ham went third with a headed double from rejuvenated Andy Carroll helping them to a 3-1 win over Swansea.

Surprise package Augsburg moved into third by beating Cologne 2-1, their fourth win on the trot. Borussia Dortmund, runners-up in the previous two seasons, moved off the bottom with a 1-0 win at home to Hoffenheim.

ITALY

Juventus stayed three points clear of AS Roma at the top after both teams drew while third-placed Genoa closed the gap with a 1-0 win over AC Milan.

Titleholders Juventus (35 points) failed to win for only the third time in 14 games this season when they were held 0-0 by Fiorentina.

Roma's match was more dramatic as they fell behind to two early Simone Zaza goals at home to Sassuolo and then had Daniele De Rossi sent off early in the second half. But two late goals from Adem Ljajic, the first a penalty, earned them a 2-2 draw.

Luca Antonelli's first-half header gave Genoa (26 points) a win over Milan, leaving them six points behind Roma. Fourth-placed Napoli (24) also came from two goals behind to draw 2-2 at home to Empoli.
