IT’S AN irony the only live theatre in London this weekend was seen at the Emirates Stadium. The compelling performance came from Premier League champions-elect Manchester City, who eased to a 1-0 victory over Arsenal through an early headed goal from an unchallenged Raheem Sterling in a crowded box. The vibrant visitors, led by virtuoso genius Pep Guardiola, gave an outstanding performance in a mesmerising opening half-hour full of verve, in which they moved the ball with ease and artistry to leave the Gunners uneasily chasing shadows. Such was City’s dominance, they registered four shots in the first 15 minutes, as they threatened to overwhelm the Gunners on the way to clinching a record 18 successive victories since December 15 — making it 25 games unbeaten, moving 10 points clear, with only 13 shows – sorry matches – remaining.
