Owen Coyle hit out at a 'beyond belief' decision after Bolton were held to a 2-2 draw at Stoke to suffer relegation.
Jon Walters netted a controversial opener against the Trotters, with the striker appearing to knock the ball out of Adam Bogdan's hands and into the net.
But Mark Davies gave Bolton hope when Robert Huth's attempted clearance ricocheted off him and into the net.
Namesake Kevin beat the red-faced Thomas Sorensen with a cross-cum-shot on the stroke of half-time to hand the Trotters the lead before Stoke equalised with 13 minutes remaining after Bogdan had felled Peter Crouch in the box after making a great initial save.
Coyle told Sky Sports: "My feelings are obviously with our supporters and our wonderful club.
"I felt that we did enough to win the game after a slow start but the decisions - you've seen them yourself today.
"For that first goal to be allowed when Jonathan Walters clearly headed the arm of my goalkeeper when he's got the ball in his hands, it was beyond belief that that could be given at this level but it was.
"And then we picked ourselves up, got 2-1 in front and had chances to go 3-1 and really put the game to bed.
"And then we allowed Stoke to come on at us with a little bit of pressure, although not any great goal-scoring opportunities.
"As it happens, Crouch has had a chance, Adam's made a great save of it and then Crouch has played it around him.
"But for me it's as soft a penalty as you'll ever get because Crouch has actually stumbled into Adam.
"Adam is not even looking at him - he's looking at where he's played the ball.
"But even then at two-each we still put ourselves up the park, Tim Ream's had a great header in the last seconds of added time, a great save from the Stoke goalkeeper which would have afforded the three points and kept us in the Barclays Premier League.
"So of course it's difficult to take, it's a range of emotions."
