Siasia recently said Obi was at par with Real Madrid ace midfielder, Luka Modric and other best midfielder in the world.
In a chat with NAN on Thursday, Siasia said: “There is nothing special between me and Obi; it’s only that I so much like him as a player.
“You can’t take it away from him that he is one of the greatest exports of Nigerian football.
“Obi started playing for top clubs at an early stage in his life and has won virtually everything he wants and above all, he is a good and committed player.
“You can also see his contributions to the national team, so, who will not like such a player. He is a fantastic lad and always playing at the top.
“If you have such a player in your team, then, you can have the compliments of others, to me he is a great export and an ambassador,’’ he said.
Siasia added that Obi has performed creditably both at the club level and the national team.
