Yup he likely deserves a shot at an elite club, which brings my other point: Newcastle may have "elite" owners, but they are far from an Elite club; not only the lack of investment, having some very glaring weak links in their starting XI, but also the way they play. Isaak (as well as Gordon) thrive in that counter-attacking style, but it can be very different at a top club especially one which sees a lot of possession.
Still, agree that he deserves that shot based on what he's been doing.
