Jose Mourinho has ordered Manchester United's record-signing Paul Pogba to show consistency on the training ground, as well as in competitive action, following his stunning display against Premier League leaders Manchester City last weekend.
The Baggies stunned the Red Devils courtesy of an opportunistic second half goal from striker Jay Rodriguez, thus confirming Manchester City's status as Premier League champions.
A week after preventing its neighbors from clinching the title in front of their own fans by rallying from 2-0 down to win 3-2, United delivered a similarly unlikely result as managerless West Brom pulled off one of the shocks of the season.
City were crowned champions with five games to spare after United lost 1-0 to bottom side West Bromwich Albion at Old Trafford.
"If I have more competition for him [Lukaku] I have more competition for the other ones and then they are not happy because they are not playing", said Mourinho.
"I saw lots of people in the moon because we won against City".
West Brom hadn't won in the Premier League since January, losing nine of their last 10 league games to slip to the brink of relegation.
19 - City have beaten every opponent in the Premier League this season, becoming the third team in history to do so, after Chelsea (2005-06) and Manchester United (2010-11).
When asked about the England worldwide, Mourinho said: "If I was you, I would go in another direction".
"We deserve top be punished, but the defeat was too heavy".
"But it is not about us and them, I think it is about the six teams".
In his pre-match press conference on Friday, Mourinho told a journalist that he only needs four points to stay second and the derby win against Manchester City last week should set their hopes on course. "Everybody is equal at the football club and we're all in it together".
Many spotted that Lukaku didn't exactly have one of the best games of his career against Pep Guardiola's side but this is surely a good enough explanation for his "poor" performance at the weekend. They were the right ones and the ones we believed in, I'm sure there are differences to how we play today compared to Bayern (Munich) and Barcelona, we survive and live by the strength of the team.
