I have to admit I don't know. I don't follow Cagliari that closely. Nandez has his versitality, but the rest I don't know..Wtf does nandez have though? And he will most probably be a more expensive one. For me, it's a complete coin toss between the two of them, although as i v said before, dumfries at least has those characteristics you mentioned.
To be clear, I wasn't advocating against Dumfries and for Nandez. I was just against Dumfries. Absolutely dreadful signing that would be.
