Chelsea have joined Manchester United's interest in Real Madrid midfielder Casemiro.
Diario Gol says Casemiro has issued a contract demand to Real Madrid.
The midfielder is aware of interest from two of England's biggest clubs.
And he wants £2.5million a year to stay at the Bernabeu.
The Brazil international is currently contracted to the club until 2021.
But Madrid may have to offer him improved terms in order to prevent him from jumping ship.
