its not just corners that they must be practicing, we had a free kick in the first half that Eriksen got it to Davies on edge of the 6 yd box, something we don't normally see
I agree most teams will get 7-10 corners a game, so you need 4 different corner moves that you practice each week,
When I coached kids at school & local village teams (both boys & Girls) at the end of training before they played match we practiced 3 kick off moves, yes it took 10-15 mins each week, but they knew if move 1 was blocked they did move 2(etct etc) we scored lots of goals or got corners from these moves, and we just train once a week, so its easy to set aside time to practice corners or free kicks (and important to practice them)
