Rome, July 19 (IANS): AS Roma sporting director Monchi on Thursday confirmed that their Brazilian goalkeeper Alisson Becker is on the verge of joining Liverpool FC, adding that the transfer fee offer from the English football giants "was way above the market average". The 25-year-old, who played in all of Brazil's run to the quarter-finals of the FIFA World Cup, is already in Liverpool ahead of his medical tests before joining the five-time European champions. According to media reports, Liverpool will pay Roma 75 million euros ($87.1 million) to buy Alisson, who had joined the Italian capital outfit for eight million euros ($9.2 million) in 2016 from Internacional. Monchi said the offer was too tempting even if it meant selling one of their best players. "First of all I want to say that nothing is finalised yet. Alisson is in Liverpool and we're at a very advanced stage, but the deal is not done yet. If everything goes smoothly, it will be finalized soon," Monchi was quoted as saying by Roma's official website. If the signing is completed, then Liverpool will smash the record of most expensive goal-keeper signing in world club football record history.
