The Lukaku sub ?
He looked about done.
He was. He had an injured toe or something, as well.
The problem wasn't that he went off, it's that someone similar didn't come on as a replacement. They lost their focal point and couldn't clear their lines.
With Everton's presence in Europe they're going to need another striker, I think. Even if they get Kone back to full fitness, they still seem a little short.
