The Blues are demanding the sum of £70 million to part with the England international as the likes of Liverpool, Manchester United and Tottenham are showing interest.
Mout is out of contract in 2024 and there’s been little or no progress with Chelsea in talks over an extension.
The England midfielder turned down the Blues’ last offer and Graham Potter’s side is unwilling to meet his reported wage demands of around £200,000, a week. Chelsea wants £70m to sell the midfielder this summer.
