That's one rough debut, especially when it was so vital that he hit the ground running.
It's hardly a surprise though, he has absolutely terrible goalscoring instincts and he can't strike a ball properly so he routinely misses guilt-edged chances. He used to bring a lot to the table aside other than scoring goals but injuries have really taken a toll on his athleticism.
I really don't have high hopes for him or Leeds. They're fans don't just see themselves as a promoted club who should savour being a PL club for as long as possible, they expect to stay up which puts big pressure on him as one of the strikers to score the goals to make that happen. I thought Leeds were terrible against us despite how bad we were, and then a 5-0 loss to Arsenal and going out of a cup to a Championship club in crisis.
There's every chance Dom will be playing in the Championship next season.
