Belgian worldwide Lukaku failed to score for the seventh successive game following his blistering start at the Old Trafford club.
One player Mourinho will be glad to see back is Paul Pogba, who has been missed since his injury earlier in the season, and it seems that United have been missing a player like him in the middle of the park - and the fans have put their dropped points down to not having a top midfielder in the side. However, he did bag a brace last night for Belgium, in an worldwide friendly, and after the game he compared his abilities in the box to a leopard.
The former Everton hitman hasn't netted in seven United games.
Fitzpatrick helps Bucs beat Jets 15-10, end 5-game skid
Fitzpatrick, facing the team he played for the past two seasons, completed 17 of 34 passes for 187 yards and was intercepted once. He finished a 15-play, 81-yard march, also lasting more than seven minutes, with his TD pass to Sims to make it 15-3.
With a price tag that could eventually reach £90m, Lukaku is under intense scrutiny to deliver at Old Trafford.
Now, it seems that when last season's star, Zlatan Ibrahimovic is back, Mourinho will consider his options and it seems that Lukaku should be anxious. "We started by blowing teams away, being dominant and creating chances".
Although he has been less than lethal in front of goal for United in the Premier League, Lukaku had a feeling his dry spell wouldn't last too long.
Xi, Duterte meet on strengthening China-Philippines ties
Since Trump took office, priorities in the region lie elsewhere, with USA focus largely on containing the North Korean threat. The South China Sea dispute will be one of the major issues at the East Asia Summit in The Philippines this week.
But he insists he is relishing the prospect and hopes Ibrahimovic can help United real in Pep Guardiola's rampant City side, who are averaging 3.45 goals per game.
"When you face a team like us it's hard for opponents", Lukaku concluded. "Him (Ibrahimovic) coming back will help us chase Manchester City".
It has previously been stated that the 36-year-old could return for the crucial clash against Arsenal at the beginning of December, and Lukaku stated that Ibrahimović's return "motivates" him as it is another "good player to add to the squad".
Marquez and Dovizioso go for MotoGP title in final race
However, he'd not have the buffer of Pedrosa for long with Monster Tech 3 Yamaha's Johann Zarco barging past on the second lap. The season finale of the 2017 MotoGP played host to the title race between Marc Marquez and Andrea Dovizioso .
But criticism is nothing new to Lukaku and he believes he will have plenty of opportunities to silence his doubters over the coming months.
