Jamie Carragher says Martin Odegaard faces a battle to return to the Arsenal line-up after Ebereche Eze impressed with a hat-trick in the North London derby. Eze was influential during Arsenal's victory over Spurs on Sunday, a result which sees them move six points clear atop the Premier League table. Speaking to Sky Sports after the game, Carragher said that he didn't think Eze's signing would be a "game changer" for Arsenal, but now he feels that the former Crystal Palace man could be the "real difference" for Arsenal's title challenge. "There was always this talk they [Arsenal] needed a goal-scorer," Carragher said. "They needed to score more goals, certainly last season to compete with Liverpool.
