Chelsea dropped its first points of the season in a 0-0 draw against local rival Queens Park Rangers, and the non-handshake between Anton Ferdinand and John Terry upstaged big home wins by Arsenal and Manchester United in the English Premier League on Saturday.
Arsenal's 6-1 thrashing of Southampton and a 4-0 victory for United over Wigan - sparked by Paul Scholes's goal in his 700th game for the club - allowed both teams to leapfrog defending champion Manchester City, which was held to 1-1 at Stoke.
A top four filled with the likely title contenders is led by Chelsea, whose perfect start to the campaign ended with the stalemate at QPR in a game overshadowed by Ferdinand's snub of Terry in the pre-match handshake.
It continued their feud following a racism row that began last season when Terry, the Chelsea and England defender, was accused of racially abusing Ferdinand in the corresponding match at Loftus Road.
Park Ji-sung also refused to shake Terry's hand.
