Fulham manager Mark Hughes claimed both West Brom goals should both have been disallowed for offside.
“We were disappointed with the two decisions to give the goals that West Brom scored,” Hughes said.
“From our point of view we felt that on both occasions players were in offside positions and therefore the goals shouldn’t have been given.
“But there you go – that is two weeks running that we have had key decisions and key moments in matches go against us. We have had another example today, so we are disappointed.
“Certainly I felt at 1-0 we were good value for that and were playing some good stuff.
“We made a change in terms of our shape today because we had a lot of personnel missing and I think initially it worked really well for us.
“But to lose two goals and having to then chase the game, it makes things difficult because we are the away side and the home side are very good and very organised.
“They have guys who will throw their heads in and scrap and fight and in the end we didn’t have enough to ask enough questions of them.”
Hughes felt particularly aggrieved about West Brom’s second goal, where Fortune was deemed by the match officials to be inactive while in an offside position as the Baggies attacked, but not when he finished the move by slotting the ball home.
“You are talking about an area of maybe 10 yards by 10 yards and apparently he is not active in the first instance, but is in the second instance,” Hughes said.
“I think we are all aware of the ambiguity of the law and areas that surround it.
“I just think it gives referees and officials an opportunity to hide behind something with decisions that they get incorrect.
“I think that has to change, but whether it will, I don’t know.”
West Brom boss Roberto Di Matteo admitted he has “absolutely no idea” how long his side can maintain their impressive form after seeing them beat Fulham 2-1 at the Hawthorns to climb to fourth place in the Barclays Premier League.
The visitors went ahead early on when Scott Carson pushed Zoltan Gera’s shot on to the post, only for it to bounce back against the goalkeeper and over the line.
But the Baggies were soon level through Youssouf Mulumbu before Marc-Antoine Fortune’s goal turned things around in the 40th minute.
