Lionel Messi is ready to put Manchester City on red alert by announcing he wants to leave Barcelona at the end of the season.

Messi, who is a graduate of the Barca academy, is believed to be in talks with the club over a bumper new contract extension.

But according to Spanish TV, he is ready to snub that and move elsewhere, with the Premier League a likely option.

The incredible news was revealed by respected journalist Francois Gallardo on the country’s infamous transfer show Punto Pelota.

Gallardo explains that Messi’s decision to leave the Nou Camp comes after he was reportedly let down by the club when promised bonuses in the past.

And he is now ready to walk out and go elsewhere, providing a crushing blow to the Catalan club, who have built their side around the world’s best player.

Messi’s current deal with Barcelona runs until 2018.
