Arsenal 2. Tottenham Hotspur 0. The Premier League match between North London’s biggest football clubs ended in favour of the Gunners, who were feisty, bright, quick, slick and aggressive throughout. The BBC says Arsenal secured a “comfortable north London derby victory”. As ever, though, the game hinged on moments of controversy. Spurs manager Mauricio Pochettino says, “The free-kick for the first goal and the first goal was obvious offside, maybe the second was too.”Is he right?
