When I say what I'm about to it's NOT arrogance.
I would add ourselves to the list - we're our own biggest threat. Get a striker in (cost permitting), a proper LB and we're good to go.
Chelsea - they've had a new manager bump, still don't rate their first eleven over us
Utd - they'll be found out when things return to normal
Liverpool - I think Klopp has run them into the ground
Leicester - might be there abouts again, depends who they hold onto
The 2 London clubs - still a long way off, and Kane is likely to leave.
That said I'm a Blue, so I'm going to say the above ;)
