According to the korean article from inven it says:
-
They are currently two teams in talks with Mata
-
The first team wants both Deft and Mata but started first talks with Mata as Deft is still with KT
-
The second team only wants Mata as their ADC is keen to have him as support
-
The first team is rumored (with high certainty) to be KZ while the second team is rumored to be either SKT or Afreeca
