Spirituality And Soccer

In our everyday lives we pray to seek divine intervention in our human endeavour
be it seeking good health, wealth, success in exams, improvement in the circumstances of an individual, group, country etc.

In the majority of cases these interventions are for the advancement of an individual or group and not at the expense of another.

The issue of prayer in Football is one that baffles me
as if both teams are praying to the same God then
surely one side will end up saying their prayers were not answered?.
Isn't this selfish? I guess it would be okay if the prayers are seeking
that the individuals involved perform to the best of their potential but
when it comes to sport most of us believe its the success that counts
and thus pray for the win.
