More questions were raised over Manchester City's capabilities in defence as Pep Guardiola's team were soundly beaten 4-0 at Goodison Park on Sunday afternoon.
Speaking as a pundit for 'Sky Sports', Arsenal legend Thierry Henry said that he thinks that City may fail to make the Premier League's top four due to their defensive frailties.
"They concede too many goals, I've said it so many times.
"If you want to be champion you cannot be that open like that, especially when you lose the ball.
"Every time they lost the ball and Everton went on the counter, Zabaleta and Yaya looked like they couldn't follow the guy, especially on Davies's goal.
"There is something that is happening at Manchester City at the minute that they need to sort out because it looks like they might not finish in the top four".
