The Belgian international played 60 minutes of the friendly against the Ligue 1 side, lining-up initially centrally in the forward three behind Jermain Defoe, but with the freedom to roam across the pitch.
He had one half-chance in the first half but Ricardo Carvalho managed to nick the ball away before he could fire at goal.
Now he's looking ahead to Espanyol at the Lane on Saturday, August 10.
“I'm happy to have made my debut, the result wasn't good and we have to work hard for next week and play well against Espanyol,” he said.
“We play at home and we want to play well in front of our supporters. I hope for a win. It's a special moment for me.
“It was great to play after training with the guys. I played 60 minutes and I hope to get fitter and fitter.
“I'm very happy to be here and I feel good.”
