Henry was worked closely with Lukaku with Chelsea and says he immediately questioned why the burly forward decided to return to Stamford Bridge.
"Is it normal that he only has seven touches [against Palace]? No, that's also not normal, regardless of if the coach likes you or not. That shouldn't happen.
"They need to move forward on that but it's a tough one to read. I'll be honest with you, I don't know how that happens in 90 minutes. But what's the solution?
"The solution is for him to find a solution to make sure he can adapt to the way they play.
"They like to press, to be active and to change the front three. He likes to stay in the middle so it makes it very difficult for him to adapt to the situation.
"But, again, why did you go and get him?"
