Perhaps but Coleman was done in a 1v1 for the first goal and Keane makes the same mistake as he did last week (when we sat deep) in losing his manThere is but I suspect we'd be in less danger at the back with players not leaving much room behind.
Keane loses a header for the 3rd goal against the ST and then loses the ST. Again, that'd happen any time you lose a striker.
The second goal - Holgate leaps out of defence and it's a Pickford howler.
So I fully agree that the system was naive and stupid but those mistakes could (and have been already) be made under a more defensive system.
