#4 Not succumbing to pressure
Two things are inevitable when you play for Manchester United - the grandeur that comes along with the charisma that the famous shirt offers and the added pressure to perform every time you play for them.
It is almost impossible to escape attention and scrutiny week in and week out with so many eyes and cameras on you. A hefty price tag does not do any favours either.
All this attention, debates and discussions are unavoidable and it takes someone with a strong mentality to withstand them. Seasoned players like Di Maria and Falcao have crumbled under it in the recent past and so far Lukaku has done well to cope with it.
At Everton, he had the liberty of being able to underperform for a few weeks but at a club as big as United, that is never the scenario. You need to learn to live with the expectation and pressure if you want to survive at this club, and with a long history of classic no. 9's and goal scorers, he already has big shoes to fill.
Although he has nearly 7 years of Premier League experience, this may seem quite a task for the 24-year-old, especially with the added pressure of everyone questioning his price tag so often. It is perhaps time we all stop speculating and let him grow more into the role.
