Those watching Manchester United's youngsters in recent years have had a lot to say about the mercurial emerging talents of Callum Gribbin.
Nick Poole, who covers United's youth team on Twitter as @ManUnitedYouth, said of the 17-year-old: "Gribbin is the most naturally talented and exciting prospect to come through the ranks at United since Ravel Morrison six or seven years ago. Unfortunately, as with Morrison, there are several attitude-related question marks that cast doubt over the likelihood of him fulfilling his immense potential."
