The Frenchman has now returned to full training for the first time since limping out of the 6-2 defeat by Manchester United and will play some part in the vital game as long as he doesn’t suffer any reaction to the injury.
"I don't think we'll know anything until Friday but I want to play this weekend," Robert told The Journal.
"I am due to train fully in the next couple of days, but I don't know how the knee will feel. It was difficult watching the games against Fulham and Aston Villa because I wanted to be out there.
"But the victory against Sunderland has given everyone a lift and our destiny is in our hands."
The news about our other casualties is less good though, with Alan Shearer and Gary Speed ruled out of the last two games and both Jonathan Woodgate and Andy O’Brien serious doubts.
