Well, Tammy played a full season and was benched at times by or for Mayoral, Shomurodov and a 17 year old unknown, whereas Cabral had a great 3rd season until his move to Fiorentina and then got injured and returned to find his teammates on holiday mode.
And that's ignoring how bad Tammy has been, goals aside. But if you're going to credit someone for scoring with his knee and dick whilst missing sitter after sitter I guess you'll be loving Tammy a lot.
This is like saying Correa had a better season than Chiesa...
