"We have invested more money than our competitors, in keeping with the history of the club," said Gillett.
"In the last 18 months, we have invested £128m on top of what has come in. That means it should be getting better.
"Now if it's not getting better, it's not Gillett and Hicks, it's the manager, it's the scouting. You have to make sure you balance out your analysis.
"There was plenty of money, so if you have any complaints, take a look at the ins and outs."
