Monaco Claim Manchester United Trebled Their Offer For Martial in The Space of a Week

Monaco vice-president Vadim Vasilyev has claimed that Manchester United more or less trebled their offer for Anthony Martial within a week, and has alsp confirmed that the total value of the transfer could rise to a whopping £58m.
The 19-year-old, who scored 11 goals in 49 appearances for Monaco, became the most expensive teenager in the world after completing his move to Old Trafford from Monaco on deadline day for an initial fee of £36m.
But Vasilyev said the “unprecedented resources” of British clubs means selling players like Martial is unavoidable.
He told The Sun:

"It’s true that the price for Martial is £57.6m but take into account this sum includes bonuses which are very realistic.
Initially Martial was not for sale, it was absolutely not planned. Since last week United started to make offers which we declined several times – £21.6m, £28.8m, £36m, even £50.4m with bonuses.
On Sunday the player got such an offer that he couldn’t have declined. He asked us to find a solution and on Monday morning Manchester United made an offer to Monaco which the club couldn’t refuse.
It’s absolutely unique. It’s the price of Luis Suarez or Neymar – the best players in the world.
Right now English football is on a different financial level and if Manchester United decides to buy somebody, it’s very hard to stop them."

It begs the question: If United really did scout Martial and rate him so highly, why on earth were they scrambling about in the last week of the window, trebling their offer?
