Query for football trials

Hello Team

I am Mridul Roy Verma, 18 years old, a budding football player and has been playing the game very passionately from past 7 years. Apart from playing at many inter-school competitions, I have also played in under 16 national team and AIFFF. In order to carry my career forward in the field of football, I have been taking training at inttersoccer Madrid SPAIN. This way I have exposure to international football and have learnt European style of the game. 

I am back in Delhi after an year's training looking for an opportunity to play in India.

Wanted to know what are the requisite for me to play in the team or give trials for the same?
