Arsenal are just a scattergun of chaos. We seemed like that under Van Gaal with our signings and the whole De Gea saga.
Arsenal are busy. Walcott, Sanchez out. Need to sort out Ozil and Wilshere futures with urgency. They've got cobbled together contigencies like Mkhi, Aubameyang, Malcom etc waiting in the pipeline. And they're waiting for all the cards to fall.
I think we'll get our man, but it may not be as quick as some people like. Arsenal will be waiting for nods from other signing, not just Mkhi (who by the way, I think will want a pay off sometime. People slag off Raiola but he fights for his clients and won't be taken for a mug)
