Real Madrid, Barcelona, Arsenal and Manchester City are expected to engage in a substantial bidding way for Kylian Mbappe of Monaco.

Mbappe has scored 12 goals in 25 matches for Monaco and he's become one of Europe's most sought after players.

Manchester City were willing to part with €47 million in the summer and his improvement trajectory could mean he eventually is sold for as much as €90 million.

Mbappe has been compared to Thierry Henry and doesn't turn 19 until December.
