He has been very unlucky with injuries so his system of 3 man defence has been disrupted.
Godfrey, Mina and potentially Holgate now then add two new defenders, you can see why fans want the 5 man defence scrapped.
If Holgate is out, Coleman comes in instead of Keane.
The 5 man defence isn't the issue for me, it's the 2 man midfield, it HAS to be 3. Iwobi and Onana did well but if you add a defensive midfielder it allows Iwobi and Onana to be more attacking and get into the box for those wingback to deliver crosses.
