I bought something on Ebay without a COA cause I don't have the money to pay for PSA/Beckett-certified memorabilia and as it turns out, most COA's are worthless pieces of paper anyway. Is there even a remote chance any of these autographs are legit?

Autographed by Cristiano Ronaldo, Lionel Messi, Zlatan Ibrahimovic, and Wayne Rooney. Are they at least decent forgeries? 

I live in North America so obtaining signatures from top soccer players isn't exactly easy first-hand. I know that it's fairly easy to get medium-top level tennis player's signatures on tennis balls if you approach them after practice.
