That is a big double-edged sword. There is a very good chance he would look worse, as he is already struggling to sync with the players that we plays with most often on the practice pitch. He is starting to find some rhythm with them, which is a two-way street.
I would have him come off the bench, if needed. I think a second game against Palace is more likely to bring out success. And, if he does not have a great impact against a poor Championship team, the pressure will be much, much worse.
