For so long last season Manchester United supporters sang that "Jose's got us playing the way United should" when, frankly, that was not the case. But it was here. This was football with power and pace and purpose - and also a 'pow' as Romelu Lukaku, their new centre-forward, scored
Football: Mourinho gets United up and running with panache

Chelsea did not secure the return of Lukaku and United did, for 75 million ($133m) plus various huge add-ons, and this was precisely the kind of fixture in which they laboured last season. Here, instead, their firepower was awesome with two late goals from Pogba and Anthony Martial giving an emphatic gloss.
With Lukaku United have more mobility and movement and suddenly a greater threat which will also help Marcus Rashford. Henrikh Mkhitaryan, pulling the strings, looks more at home in his second campaign, and Matic was all clever movement and creativity.
Furthermore, Mourinho has daunting resources. His bench included Ander Herrera, Jesse Lingard and Martial while another important signing, Victor Lindelof, was not even among the substitutes after, admittedly, struggling in the midweek Super Cup defeat in the humidity of Macedonia against Real Madrid.
United's first goal summed up what Mourinho wants and what United lacked last season, in fact.
It came as Matic snapped into a challenge, closing down Pedro Obiang as he dawdled and then Rashford slipped the ball through to Lukaku who struck it first-time on the run, with it cannoning off the post and into the net. Bang.
Pogba, dominant in midfield, led the charge after halftime. Lukaku steered a header from a freekick past a rooted Hart. Replays showed some bizarre behaviour from the West Ham left-back Arthur Masuaku who was grinning, laughing, bending to tie his laces. Everything, in fact, except doing what he is paid to do: defend.
More goals came. Martial then ran on to one final smart pass from Mkhitaryan, before he was substituted, to spring past the West Ham defence and side-foot beyond Hart. Then Pogba curled in a 20m shot. The scoreline was emphatic. Just like the performance. It was music to the fans' ears.
