In the current lineup you picked out the higher potential players. Comas the RCB you mentioned and Mingo the LCB, but he is below the level he showed pre-injury right now.
I was just going to post that I expect Matheus comes on in midfield for Oriol at some point and I see that it's happened (he is not one to keep an eye on
).
From the bench Angel and Ilias (both 16) are very highly rated. I expect Angel to get some minutes so watch out for him.
There is just too many injuries right now. From midfield alone the team is missing Jandro, Lucas de Vega and Gavi, not to mentioned Ilaix who is with the first team.
