Manchester United are close to signing Real Madrid midfielder Casemiro for a fee that could rise to 70 million euros (£59 million, $71 million) according to multiple media reports on Friday.
The BBC and The Athletic reported United will pay an initial 60 million euros and make the Brazilian international among the top earners in the Premier League with a four-year deal along with a club option to extend that contract by an extra season.
Even if talks progress smoothly over the weekend, Casemiro is unlikely to be registered in time for that match.
The 30-year-old has won three La Liga titles and five Champions Leagues during nine years with the Spanish champions as he formed a formidable midfield trio with Luka Modric and Toni Kroos.
