Paste value in Array chunk

I have 12 teams registered in a table and I want to divide them into 3 groups. So I get these teams in array form and I use array_chunk to split them, which will form the 3 groups of 4 teams I want.

But I am not able to access NAME_TEAM , I have tried several ways and I can not. Could someone help me?

See how the array is mounted.
