Lionel Messi turned down an offer of a €100million (£88m) signing bonus from Manchester City to pen a new deal at Barcelona. The Argentinian super star put an end to suggestions he would leave the Nou Camp last month as he finally signed a £500,000-a-week contract which will tie him to the club until 2021. But, according to Spanish outlet Marca, that followed a huge proposal to bring Messi to the Etihad.
