Joe Hart erred again in goal for Manchester City in their 1-1 draw with Everton at Goodison Park.
The England No.1 attempted to come and clear the ball, only to punch fresh air, and see Steven Naismith gladly head home into an open goal.
The assist by Leighton Baines means the left-back becomes the Premier League’s highest assist-maker for a defender of all time.
Manchester City had only taken the lead moments before when David Silva’s attempt at goal was blocked, only to fall fortuitously to Fernandinho, who cooly headed his side in front.
Hart’s mistake could prove very costly for Manuel Pellegrini’s side with fellow title rivals Chelsea winning 2-0 at home to Newcastle United.
With the development of David de Gea into a top class goalkeeper and the addition of Thibaut Courtois to the Premier League, Hart’s standing in the goalkeeping world doesn’t look as strong as it once did.
