My opinion is pretty much the same as Dragana's (tbh, it seems to rarely differ
), as I mentioned in the Cassano thread.
However, if the deal is to take place, there are a few positives, including Del Piero's ability to bring variety to our squad which currently is dominated by "goalscoring" forwards (which Dragana has already touched on). One factor which may or may not prove valuable is Del Piero's experience at the top level and his set piece taking, which is very good.
However, personally, I think Cassano would be a better acquisition for the long term, though I still have some worries over his mentality/attitude.
