Coventry City manager Steven Pressley said that his side have to defend corners after drawing 2-2 with Barnsley at Sixfields.
Pressley was not happy with the defending at set pieces which cost City two goals and the City boss told Nick Connoll: "It's two points dropped really and if we are serious about achieving this season then these are the gameS we need to win.
"Their second equaliser was certainly beyond the recommended added time but we still have to be able to defend the corner.
We've been undone by a special free kick and a corner which have ended up being the difference between three points and one point."
