I think the big problem in the Mourinho era was fitness. We started games ok then ended up clinging on for dear life. Every single time he said "I didn't tell them to do that"If you think that's hard do believe you didn't fucking even watched a game under Mourinho.
He's many many things but he wouldn't say that IMO. Even in games we won he'd say it. He's so egotistical I would expect him to take credit for those games, not claim it wasn't his doing.
The issue is, he should have been aware of it and fixed it.
