Arsenal and AC Milan underlined their championship credentials this weekend in England and Italy, while Real Madrid closed in ominously on Spanish leaders Real Sociedad.
Having seen Manchester United close the gap at the top of the premier league to two points with a 3-1 victory at struggling West Bromwich Albion, Arsenal responded with a 4-0 drubbing of Birmingham City.
Milan were equally impressive, retaining top spot in Serie A by ending Bologna's 100 percent home record with a 2-0 victory.
French striker Thierry Henry claimed Arsenal's first and last goals to chalk up his 100th strike for the London club, with midfielder Robert Pires and defender Lauren scoring in between to sink Birmingham.
Manchester United notched up only their third away win of the season at West Brom, Dutch striker Ruud van Nistelrooy, England midfielder Paul Scholes and Norwegian forward Ole Gunnar Solskjaer finding the net.
Chelsea stayed third, eight points behind Arsenal thanks to a 4-1 home victory over London rivals Charlton Athletic.
Second-half strikes from Ukrainian Andriy Shevchenko and Brazilian Serginho gave Milan victory at the Dall'Ara stadium where Bologna had won their previous seven games.
Milan lead the standings on goal difference from city rivals Inter who also reached 36 points with a 2-0 victory over Modena with goals from Alvaro Recoba and Hernan Crespo.
The win came at a price for Inter, however, as Crespo was taken off on a stretcher with a groin injury.
