Looks like another similar situation with Swizterland -5.5 against Gibraltar.
Swiss 2-41 in last 43 games covering a -5.5 line. However, Gibraltar has failed to cover +5.5 like 40% of the time in their last 20 games or some shit like that.
Total is 5.5.
When they play a quality team/power in Europe, they've easily given up 5, 6, 7, 8 or 9 goals.
