104 scholes use or no?

Have 3 great CMS at red rank untradable already, 105 ww you're, 104 tt xabi Alonso and 101 retro zidane.

I use a 2 cm formation as well with zidane on the bench.

I have 90 shards rn and with thunderstruck expiring this week I am in a dilemma

I got scholes from 102-105 thunderstruck pick but I don't really need him. My two best CMS are defensive but I also have zidane who is great and offensive

My CBS are my weakest link tho, I have 102 pau cubaesj purple rank and 101 red rank retro kompany

I'm wondering if I should exchange scholes for shards to try get 104 injgo Martinez. Should I or no? (I have already claimed van persie)
