Arsenal vs Chelsea: London teams battle to keep pace with Man City

Arsenal and Chelsea face off on Sunday, with one or the other losing their perfect start to the Premier League season. Arsenal has begun its title defense with a 3-0 win over Coventry City and a 1-0 victory against Aston Villa. Chelsea, under Xabi Alonso, has won its last two matches but has shown defensive weaknesses. Arsenal has won the last three encounters between the two teams, and a win for either will keep them in touch with Manchester City, who sit at the top of the table.
