I read in The Times yesterday that some boffins have said that building a wall impairs a goalkeeper more than if there wasn't one. They reckon that a goalkeeper is about two inches away from where he would be if he wasn't unsighted by a wall.
But we know that anyone taking a free kick has less to aim at with a wall and so it is harder for them.
Could you imagine Bomber taking a twenty yard free kick with a clear sight of goal?😂
I don't expect to see team's defending a free kick without a wall anytime soon.
Boffins eh?
