Eto'o clashed with Samp coach Sinisa Mihajlovic in his first week with the club.
Obiang said: "Nothing really happened, it was just a misunderstanding between them. The Coach had a certain idea to put forward and in that moment Eto'o didn't agree. Then they talked it over and understood each other.
"As they both live in the same hotel, they have an excellent rapport now."
