Stefan Maierhofer has hit out at Wolves after joining Bristol City on-loan this week.
He cannot understand why Mick McCarthy has been so reluctant to give him a chance, especially with Wolves the lowest scorers in the Premier League this season.
The 27-year-old admits the whole experience has left him feeling infuriated as well as confused.
"I don't have a clue why I've not been in the team. I work hard in training, yet others get to play," Maierhofer said in the Daily Star.
"Why have Wolves signed me only to not use me? Kevin Doyle cost £6.5million, so he has to play yet he has just got six goals in 25 games, which is not a great deal.
"The manager told me I lacked match practice after my operation.
"Then Andy Keogh came back from a three-month lay-off, trained for two days and then played against Bolton and Manchester United.
"I feel like they are taking the p*** out of me."
