You have to be blind to not see huge progress Legro has made since becoming a christian. The christianity thing will help him as professional footballer if he continues to believe, but of course he doesnt have to pray for scudetto, as that would be pretty stupid indeed
But i believe there would be much more good and satisfied people if everyone turned to God. And that probably works for footballers too.
P.S. no, i`m not a christian myself. i was raised in such family though.
