9. Tom McIntyre - Bradford
Showing signs of rejuvenating his career in season-long loan with Bradford. Made four appearances and started the past two games, picking up man-of-the-match plaudits against Rotherham at the weekend as Bantams fly high in League One. | None
10. Toby Steward - St Johnstone
