Question marks remain over Lukaku's performances against elite opposition, though, with the 24-year-old having failed to score against any of the Premier League's top eight in 2017-18.
The Belgian striker hit the ground running at Old Trafford following his move from Everton in the summer, scoring seven goals in his first seven league games. Mentally he's strong and I'm sure he will continue to score goals. For a young player it's not an easy situation because everyone expects you to score in every game.
"But if I was one of you I would ask if the Manchester United manager agrees that Scott McTominay had a fantastic performance and my answer would be yes he had a fantastic performance".
He's managed to net 12 goals in the Premier League this season with recent strikes coming against Huddersfield and Stoke, while he's notched at the Terriers as well as against lower league sides Yeovil and Derby in the FA Cup.
"Alexis is working really hard", he said. "But we play both for top-four and it's a big game independent of what is at stake". "I am happy he is a team-mate".
Romelu Lukaku will do big things at Manchester United, says Nemanja Matic

Matic, however, is delighted to have the Chile global at the club. How will Manchester United use Sanchez best within the dynamics of their set-up? I think that might start to excite some of the Manchester United supporters. Of course, he lost a couple of possessions, but he gave us also stability - because we had a good percentage of ball possession for the way we play a match away from home against a good team like Sevilla.
'We can understand he's from Madrid and would be playing for a team that would be challenging for the Champions League season after season'. He looked a senior player, he looked a player with great maturity, with tactical sense, with a sense of responsibility, good in possession, good in the pressing.
