Yes I think he's doing a terrific job but that's my opinion!
He was screwed by the owners with the Carroll saga, he has 1 available striker, he has played some of the youngsters who have come on very well, we are unbeaten in 7 games......so yes, in my opinion he is doing a terrific job and the signs of improvement are there and bode well for the future!
Each to his own I guess. Personally, if someone had told me that we'd be in the bottom half of the table heading towards December and out of the league cup already thanks to Brendan's old club, I wouldn't have thought it was 'terrific' at all.
