It's unfair to compare Cavani with Falcao.
Falcao is a League 1 level striker (so, we have EPL, Championship, League 1).
He can't stay on his feet for long enough to score a goal. Absolutely woeful. I can't explain just how bad Falcao was/is.
It took LVG about half a season to work out that Falcao was terrible. It took Jose 1 pre-season to work the same thing out. If I were his employer, I'd take him to court to refund a percentage of his wages...he's that bad.
He is masquerading as a pro footballer. And lets not forget that he is the most blatant mercenary I have ever seen in all my years watching football. He will literally play for any team in any country, which pay the highest wage.
He has no loyalty to any club. Just pay him a big wage and he will join you....and score zero or few goals.
If I had to bet money on who would score more goals: a 16 year old boy or Falcao, I'd bet on the 16 year old.
Rant over....
With Cavani, he is clearly strong and powerful. But his composure in front of goal is repeatedly letting him down. Will he get better? Not sure. Ibra is now gone and perhaps the pressure now on Cavani is too much for him to handle. Only time will tell.
