Are people saying "Tella isn't good enough" as in: "I've seen enough of him to inform me that he'll never reach premier League standard" or are they saying it as in: "he's not good enough yet but still has potential to reach premier League standard"
If the latter, then he's a decent enough 5th choice, if the former then why have Saints bothered listing him in this season's first team squad in the first place...?
