Great!
I hope none of them returns, at least not as a DP.
As far as Soteldo is concerned, in my view he's worth no more than a TAM deal for TFC. He's not what we need for a DP, and in this has a part that he and Poz can not coexist as needed on the field.
Now, if Poz would be gone by next season, then Soteldo may be worth to stay as a DP... but this dependig again on who the other 2 DP-s will be.
