Former Manchester United defender Rio Ferdinand is worried about how close Manchester City have come to Arsenal in the Premier League title race.
The Englishman is also concerned about the Gunners' injury woes as they chase a long-awaited title under Mikel Arteta.
Arsenal, who were tipped to claim the title this time around after years of disappointment, have dropped points in three of their last five games. They drew 2-2 with Sunderland, 1-1 with ten-man Chelsea, and lost 2-1 to Aston Villa in their most recent matches.
