"I was determined to go back in the Premier League and not bleat about referees or linesmen," he said after the 2-2 draw at St Andrew's.
"I've seen their centre-forward jumping on my goalkeeper and stopping him getting up. I think the referee should be seeing that, because everyone else is seeing that.
"After he makes the save, he's still lying in the back of the net. The referee and linesman have missed it which has cost us dearly and it's a shame because he produced a fantastic save.
"I think after looking at the two games we are better equipped than we were the last time we were in the Premier League. I am really pleased with what I've seen."
