Are we ranking them by their ability to play their position or by importance to the team? I.e if one of them were to get injured, or sold, how big of a loss would it be.
For me Boruc is the most important player to have fit in the team. When Boruc has been out we've imploded. He isn't a fantastic keeper by any means but he's certainly solid. The defence looks comfortable with him between the sticks. The most important factor is that we don't have a replacement of a decent standard at all when Boruc's out. After that I will go for Shaw, Lovren and Fonte. Clyne at left back or Yoshida instead of Fonte or Lovren weakens the side noticeably.
1. Boruc
2. Shaw, Lovren, Fonte
5. Lambert
6. Rodriguez, Lallana
8. Davis, Schneiderlin, Clyne, Wanyama
If I rank them by ability in their specific position, instead of importance to the side, then the rankings would look different:
1. Shaw
2. Rodriguez, Lallana
4. Lambert, Schneiderlin
6. Lovren, Fonte
8. Clyne, Davis, Wanyama
11. Boruc
This does show we desperately need an extra keeper.
