Mikel Arteta accepts Arsenal may have to win each of their nine remaining Premier League fixtures to be crowned champions as he prepares for the “most beautiful part of the season”. The second-placed Gunners sit two points behind leaders Liverpool ahead of a hectic April schedule following Sunday’s dogged goalless draw at title rivals Manchester City. Manager Arteta, who also has a two-legged Champions League quarter-final against Bayern Munich to consider, wants his players to embrace the challenge, beginning on Wednesday evening at home to relegation-threatened Luton.
