Martial’s switch came as something of a surprise due to the fact that the 19-year-old remains unproven and has only completed one full season with AS Monaco.
He managed nine goals in Ligue 1 last term, and is yet to make his France debut. In completing a move to the Premier League, the forward became both the most expensive teenager and the most expensive Frenchman ever.
While Martial will doubtless be delighted at having secured a big-money move to join up with Louis van Gaal, one of his new Premier League rivals has issued a warning.
City defender Mangala has backed Martial to improve quickly, but has noted that the striker’s life will never be the same again.

“Martial will be looked at differently, because Manchester United bought him so expensively,” the stopper began, as reported by Le 10 Sport.
“He must concentrate on his football, everything else is a part of the world of football. We see great fees in transfers. When we compare it to the past, we can see that it’s going a bit too far.”
Mangala himself knows how a bit transfer fee can transform perceptions, having never quite managed to establish himself since leaving FC Porto for £32 million in 2014 [BBC Sport].
