Japan would suit very much.

la liga is the only league with shorter players i can find!

He should try a more technical league in Europe or Japan.

I think he's ready to go over. 

Nah, he would run the risk of limiting offers on the table. Mariners should have had an auto extend clause in his contract, so it's really on them. If we had a proper domestic transfer system, those sorts of clauses would be the norm. 

Does he sign a contract just so mariners can get a fee? 

Available on a free? European clubs don't know how much they can rob and get away with it here.
