I guess internal treatment matters most when it comes to performing well on field as footballers. Just like you said, Corruption has eaten deep in football as well and I came to know this thru a close person who is a footballer. You just see them playing on field like they're happy but sincerely they're depriving them of somethings which is depriving them their full concentration and happiness too. I don't know if that's enough excuse and reason though.
I wish us success and tension-free match on Tuesday
