#2 Inability to implement a coherent style of play
What exactly is Manchester United’s style of play under Mourinho? Are they a counter-attacking unit in the mould of his Real Madrid side? Are they a gegenpressing side like Jurgen Klopp’s Liverpool? This is perhaps the biggest issue that Mourinho has failed to address since he arrived in Manchester.
The style of play since Sir Alex Ferguson left has been a mix of contrasting styles; cross-and-hope under Moyes, sleep-inducing possession football under Van Gaal and the present confusion under Jose.
He has chopped and changed many times and still looks unsure of his best XI in his third season at the club. The players are still unsure of what the system is and what their roles are within this system.
This confusion has been a huge reason why the football has been boring, staid and misery-inducing. United fans have been treated to a steady diet of ground-out victories against opposition that should have been blown away, ambitionless draws/wins against fellow top-level opponents and the increasingly regular beating by well-drilled sides (think Sevilla and Manchester City last season and Brighton and Spurs this season).
Pundits, fans and even players are confused as to what exactly United under Mourinho is and this will be one of the biggest things for which his tenure will be remembered.
