Chris Sutton believes that Chelsea's struggles in front have become a 'concern'.
Graham Potter's side were unable to find the net on Sunday as they suffered a 1-0 defeat at home to Arsenal.
Chelsea have scored just twice in their last four league games. They have scored 17 times overall in the league, which is significantly fewer than Arsenal's 31 and Manchester City's 39.
Former Chelsea player Sutton was also concerned about Potter's post-match interview in which he compared his team to Arsenal's current situation.
