Andy Thompson
Indeed, quite often watching MotD it will be the fullback that plays a striker onside to score the vital goal. The centre backs are obviously very adept at moving as a unit, but modern fullbacks can get caught out as they're haring up and down the flank trying to do the work of two men.Defensive positioning can be taught, thankfully -- right back (along with left back) is the most difficult position to play in the modern game, tactically and positionally.
Last night it was Borthwick Jackson of Man Utd playing Costa onside for the last minute equaliser. The pundits ignored that and blamed Blind for diving in which is also true, but BJ should not have been so deep. Happens all the time.
