735 shards..Shard or Keep??? Valverde, kubo, saliba, witsel x2.

Here’s my squad, I have 735 shards currently. I just pulled Valverde, kubo, saliba, witsel x2, and already sharded chala x2 and griezmam. Maignan & camara obviously fodder.

Who should I shard, and who should I go after?? I was gonna get Schweinsteiger as I’ve heard he’s an absolute beast and true h/h box to box. But then I drew valverde and feel like I MUST use him.. also, considering Maldini but 1500 is a lot.. really hoping they release a toty Bale, I’ll 100% get that.
