May as well have a guess:
1. Lomax
2. Makinson
3. Turner
4. Percival
5. Swift
6. Burns
7. Walsh
8. Walmsley
9. Roby
10. Amor
11. Vea
12. Wilkin
13. LMS
14. Fages
15. Peyroux
16. Tasi
17. Savelio
18. Thompson
19. Richards
20. NEW SIGNING
21. Greenwood
22. McDonnell
23. Haggarty
24. Knowles
25. Charnock
Lomax, Makinson, Percival, ???, Swift, Burns, Walsh, Walmsley, Roby, Amor, Vea, Wilkin, Turner
Fages, Tasi, Savelio, Greenwood
McDonnell, Peyroux, Thompson, Richards, LMS, Knowles, Haggarty, Charnock
After seeing it written down like that I definitely think a centre should be our no.1 priority, assuming Turner will be used elsewhere.
If Turner is to play centre and Wilkin at 13 then I'd probably say another 2nd rower is needed.
