Mikel Merino scores the only goal as Arsenal beat Chelsea to move 12 points behind Premier League leaders Liverpool.

Mikel Merino’s first-half header was enough to see off Chelsea and take all three points from a dominant display in this London derby. The Spaniard headed in Martin Odegaard’s corner, and nearly netted a volley in the second-half, as we took all three points at Emirates Stadium

Arsenal are unbeaten in each of their last six Premier League games versus Chelsea (W4, D2), their longest run without a league defeat against them since a run of 19 matches between 1995 and 2005. The Blues are in danger of losing three consecutive top-flight fixtures at the Emirates for the first time.
