That argument stood 2 managers ago. We keep changing the players and getting the same results.
When we are sacking managers whilst replacing the players then those two points don't correlate. You can't blame the players all the time when their manager is getting sacked, last 3 managers sacked and Silva now waiting to be.
I agree the players do need to put a shift in , absolutely. But as the stats show, Silva as manager doesn't have a team fight for him. That's as much a sign about his ability than anything else.
