London, Feb 13 (IANS) In a major blow to the Arsene Wenger-managed football club, Arsenal striker Alexandre Lacazette has been ruled out for at least six months after undergoing an arthroscopy on his left knee here on Tuesday.

"The minor procedure was a success and he will now undergo a period of rehabilitation. It is envisaged that he will return to the squad within four to six weeks," Arsenal said in a statement.
