#1 Undermining his backline in various ways
Everyone knows how frustrated Jose Mourinho was when he couldn't convince Ed Woodward to sign a centre-back in the summer transfer window. It went public as most things have with Manchester United over the last couple of years.
However, Mourinho, in an in-your-face sort of manner, has responded by starting a central midfielder in the backline on 3 occasions already this season. Elsewhere, it would be unheard of but at Manchester United, it is just one of the things that the club just does every once in a while.
To add to this, Mourinho keeps putting the kibosh on his players' confidence by airing his grievances in public. After their dull performance against Valencia in the UEFA Champions League, Mourinho took a potshot at his defenders once again.
“The players tried. They raised the level of their efforts. They raised the level of their intensity in spite of the fact we don't have many with that intensity. We don't have the technical quality to build from the back."
"We tried to do something we did well which was to stop a fast team on the counter attack. We knew we wouldn't create 20 chances.”
Mourinho is starting to sound like Graeme Souness and any team could do with a Souness being at the helm.
