I wasn't referring to your comment personally just in general they've both played relatively few games to truly judge their abilities yet and in Ilaix's case, he's started 1. So was agreeing with your remark about sample size.
Need a sustained period of time and a long run of games, however very unlikely Puig gets that under Koeman. Ilaix could well do though, depending on whether Wijnaldum is signed or not.
