The Belgian had an impressive time out with United last night on his debut for Mourinho’s tutored team as he continues his goalscoring mark at the club.
Lukaku netted his sixth goal in as many games for United, back in the competition for the first time in two years, to help them secure all three points at Old Trafford.
Jose Mourinho handed Paul Pogba the captaincy, but his time wearing the armband was shortlived as a hamstring injury forced the midfielder off in the 19th minute.
Any hope of a Basel comeback was snuffed out 10 minutes after half-time when Lukaku powered a strong header into the corner.
A fine night’s work for Mourinho’s side was capped with seven minutes remaining as substitute Marcus Rashford curled home a third.
