Milosevic, 27, joined Forest as a free agent earlier this month and made his third appearance for Martin O'Neill's side against the Baggies as the two clubs played out an enthralling 2-2 draw.
A Stefan Johansen own goal gave Forest the lead before Jacob Murphy scored his first goal for West Brom since joining the club on loan from Premier League side Newcastle United. Ryan Yates made it 2-1 with an excellent finish.
But Dwight Gayle controversially won a penalty to the anger of Forest fans, which Jay Rodriguez scored in the 89th minute to earn a point. Sweden international Milosevic reacted angrily on Twitter after the match, claiming Forest deserved more.

Milosevic combined with fellow new signing Yohan Benalouane at centre-back, as he continues to impress in his early stages at Forest. He has previously played for AIK, Besiktas and Hannover.
Nottingham Forest fans reacted to Milosevic's Tweet, praising the Swede but also venting their anger at the result with replays showing little-to-no contact on Gayle before he flung himself in the air.
