I don't think Cavani ever looked impressive either though, and I see Nunez in the same kind of mold. A potentially high level Tier-2 striker who scores (and also misses alot), with glaring flaws that you sign because you can't get the Tier-1 guys.
In previous years with guys like Etoo, Suarez and False 9 Messi we never really needed to look at that level. But now we do, albeit not out of desperation as high scoring inverted wingers are also necessary for us, which we should prioritise in with Dembele and Adama leaving.
