Danny raises a good point we need to see the attributes

With there being a 4 year age difference is it that the scout player is knackered by half time?? Whereas the other guy is trucking on throughout the match??

As far as defenders taking yours corners in my second season i set my goalie to take corners to maximise the number of people you've got in the box as you never get the other team scoring a break away goal. I only changed this as i wanted outfield players to get the extra skill points assists get you. It was hilarious seeing my goalie on the assist charts early in the season though
