Twitter goes wild as Kylian Mbappe joins Paris Saint-Germain

Paris Saint-Germain have reached an agreement with Monaco to sign striker Kylian Mbappe on a season-long loan with an obligation to buy and make the France international the most expensive teenager in football history.

PSG's deal with the Ligue 1 champions includes a compulsory purchase option of €180million, which will be triggered at the end of the season, with the player agreeing terms on a contract until 2022.

Here's how twitter reacted:
