at least make it realistic to refuse it...

i got an invitation for a freindly which started 5 minutes after that and did not even have a real chance - won the friendly and the league match but lost an important champions league match because my whole team was exhausted afterwards. i was lucky no player got injured...
this guy is in my league and i will kick his little a** in tomorrows match against his team `--´

it would be much better if you could only invite a few hours or maybe one day before kick-off...
