The Chilean has struggled to find his best form so far this season, and a former Gunners player believes he knows why
Alexis Sanchez has struggled after failing to secure a move from Arsenal to Manchester City but the Gunners must do what they can to keep him, according to Emmanuel Eboue.
Chile forward Sanchez appeared destined to end his three-year stay at the Emirates Stadium by joining Premier League rivals Manchester City in the previous transfer window.
However, Arsenal were not able to capture Thomas Lemar from Monaco, resulting in Sanchez remaining in north London.
