It won't get any prettier
Jose's teams are always built from back to front and have consistently placed a heavy emphasis on defending.
United's rearguard isn't as bad as you might think - they had the joint best defence in the Premier League last season. It's the other end that was the problem all year long.
It's not exciting. It's not flamboyant. It's not remotely entertaining. But unlike Van Gaal's all too similar playing style Mourinho's actually works. They will score more goals - but not many more.
