The "underwhelmed" comments (underwhelmed because they've probably never heard of him or seen him play) and plenty on Twitter claiming he is "not good enough" because we are suuuuuch a big club.
Grabban is the kind of striker we have been crying out for, a pacey finisher that can play off the target man (Ulloa) or come on late against tired legs and make an instant impact. The people writing him off before he has even signed should **** off and support United.
