JB, as a keeper, it is not always easiest defending the in-curling cross. Plus, when an -in-curling cross is headed, the natural trajectory is for the ball to head downwards whereas an outswinger is harder to control. But yes, it is the fullbacks that tend to provide the crosses as overlappers and if you play with "wrong-footed" wide midfielders, the advantage is that you have two possible options from wide areas. It doesn't always work so well and certainly is not so good from a defensive perspective when those midfielders tuck in because they are then defending on their "unnatural" side.
Go strong, it's going to be a great day in Adelaide. One of the wonderful stories from this season concerns a work colleague of mine, who until this season was a Parramatta Eels league fan. She has become totally captivated by football and by the Wanderers, absolutely raves about the passion and atmosphere created by the fans and the RBB. She feels part of something very special. In the space of the season she has completed two road trips to Melbourne, one to Brisbane and hasn't missed a game at Wanderland. She booked a flight to Adelaide last week as a "speccy" and is now preparing for her first A League Grand Final. She described being at Sunday's game as the greatest sports experience of her life.
That's the kind of story that makes this a "wanderful" season.
the main theory for having left-footed players playing on the right and vice-versa is because they will have an inclination to cut inside. That's all well and good but it is important for those players to have a naturally-sided (ie left-footed left sided) over-lapping fullback who can utilise the wide space created by the midfielder. Leicester have used Riyad Mahrez on the right to great effect for most of the season.
