Transfer news: Arsenal, Manchester United and Tottenham warned Monaco starlet will Kylian Mbappe will cost €60million

Monaco have slapped a £51m asking price on the head of Arsenal, Manchester United and Tottenham target Kylian Mbappe, according to reports in France.

The 18-year-old is fast becoming one of the most wanted players in Europe and his performances have led to comparisons with Gunners legend Thierry Henry.

Arsenal, Manchester United and Tottenham are reportedly all watching the forward, but his admirers are said to stretch to Germany and Spain too.

However, any club hoping to prise Mbappe away from Monaco this summer will, according to reports in France, have to stump up €60m (£51m).

The youngster's club are in no mood to sell one of their up and coming stars and it is hoped such a high asking price will enable them to keep hold of him for another year or two.
