no, let it be deleted if he is not notable. I thought He comes under notability criteria as he have played for Mohammedan and FC Kochin (Let me Confirm whether he have played in 1st division). Anyways he will be the Head Coach of Gokulam Group's FC (Name is not confirm, They are considering names with Kerala in it. ) in I-League.
Even if he did, FC Kochin played in the NFL and that wasn't fully professional, only I-League was. He isn't notable. I will move into your userspace so your work doens't go away.
Minerva were not an I-League side when they played in the Durand Cup and if they were, the only other "I-League" side in their group were DSK Shivajians and Sporting Goa.
