Well i've never used him in my saves, but he seems to be more of a championship player, i don't think he would do much in the premiership. Just taken some screenshots of his stats in 2013, and his history.
As you can see in the history picture, he is more prolific in the championship than the premiership but if you can get him cheap then by all means give him a go
I'm guessing your still in the premiership right? You could try and get Fraizer Campbell, he is quick and he scored 8 goals in 11 games for my West Brom side since january. If you can get him you could try and get Emmanuel Emenike. He is quick, strong, agile and he can finish! And he is cheaper than Ched Evans. Could try and also get Garra Dembele, he is my goal scoring machine on this West Brom save.
Take you pick, but i wouldn't choose Ched. But that's just my opinion
Well i personally have never brought him just simply because I don't really need to, but some people on the link i will post have had good experiences with him.
