You really misunderstood me.I said "exciting football" not "better football".In the last 45 minutes(including extra time),Greece were definitely creating most of the moves.And as far as I remember,I distinctly heard the commentator saying at 100th(or some time around) that Costa Rica had had 2 shots on target,whereas Greece had 10 shots on target.Granted,I didn't watch the full match but the time I saw the match(60th min to 120th min),Greece were definitely playing more exciting and attacking football,though the finishing quality was really poor.
Notice also that I said "I wanted Greece to win"(which is based on my personal opinion),I didn't say "Greece deserved to win."
Peace.
