Manchester United eased back into Champions League life as Marouane Fellaini, Romelu Lukaku and Marcus Rashford put Basel to the sword.
Last season was just the second time in 22 years that the three-time European champions were without a place at the continent's top table, but May's Europa League triumph brought a much-needed return.
United's first Champions League match in 644 days ended in a straightforward Old Trafford victory as substitute Fellaini, in-form Lukaku and substitute Rashford kicked off Group A with a 3-0 win against Basle.
