Well, if we're to go by transfermarkt alone (manually including his latest app/goal) Borrigol has 58 goals in 212 serie a appearances giving him a ratio of .27 goals per game. Matri has 55 goals in 171 appearances giving him a ratio of .32 goals per game.
Transfermarkt could cuite possibly be wrong though, but it's the best I could find that offers a decent overview.
