Arsenal have been dealt a setback with Noni Madueke expected to spend at least six weeks on the sidelines after injuring his knee in Sunday’s 1-1 draw with Manchester City. Noni Madueke, a 23-year-old England international, who arrived from Chelsea during the summer transfer window, was withdrawn at half-time after feeling discomfort early in the game. Although initial scans suggest he has avoided a dreaded ACL injury, further tests are needed to confirm the full extent of the damage. Speaking ahead of Wednesday’s Carabao Cup tie with Port Vale, Mikel Arteta admitted the winger could be out for several weeks. That would see him miss a run of important Premier League games as well as Champions League fixtures, including a potential return against Sunderland on November 8.
