He won't start against Blackburn. He may come on at some point. But I wouldn't be surprised if Brighton recall him due to him not getting enough game time under Harris.
As I've said before, we don't see what happens during the week at the training ground etc for Harris to decide the starting 11. But surely Molumby and Bod have shown enough on international duty this week to get in the starting 11 or more then 10 mins as a sub.
Look at McCarthy at the win against WBA in the cup, he looked very decent and in some parts of play, looked a lot better defensively then Romeo, but again, he won't get his chance until Romeo get injured or is suspended.
I don't want to come across as negative, but for every good decision Harris makes, there is always a shit one that follows very closely. At Blackburn, we will see Williams and Ben start in the middle. Bod on the bench and McCarthy left at home or he can come along and carry the waters.
