Mark McCammon has criticised Dennis Wise for freezing him out at Millwall.
The 26-year-old striker is on a month's loan at Brighton and believes he has no future at The Den.
He said: "When I was left out of the Millwall team, Dennis Wise and Ray Wilkins told me I needed to get into better positions and to work harder.
"But that was rubbish, because the ball was never coming to me. I much prefer the way we play at Brighton, where the ball comes forward quickly."
