I'm yet to see Holla in a 4, but Stephens' is repeatedly just behind the ball, just out of position, fouling his way out of trouble.
He also takes just too long on the ball.
It could be because it's the start of the season, and he's not 100% confident after such a long time off.
They could all...
I know I'm pretty much on my own here, but from Friday's game I think Stephens' place is most under threat.
I have no idea how Holla managed the previous 92 minutes, but a few more passes like that one should she him starting the 4-4-2 games.
