What player do i need to buy to complete my team?

[Roberto Massa]

Attached you can find my team.
I've 75 tokens left and i'm not sure if it's no longer necessary to buy a DC or MR\AMR( i can't find it anywhere) from osservatory section and the other one from normal player market.

Please help me what do you think about this.
Thanks in advance
