"We deserved what we got - nothing," Robson said after the game.
"We were very poor, did not pass the ball and had a very low energy level.
"No disrespect to the lads we took off at half-time, but if I could have used 11 substitutes I would have done.
"The way the other results have gone have more or less put us down.
"Mathematically we can still stay up and we'll prepare well for the next game with West Ham and hope we win both of our final games."
