i personally think he is great, if you look at who he has bought,
samba= £400,000
Nelson= Zilch
Santa cruz= £3.4 m
Mccarthy= £1.8m (18 prem goals last season)
Bentley= £400,000
there may be more but thats amazing buying! although tactically he can be a bit slow at times leaving a change too late, but i would be gutted if he went so that says it really
