Chelsea and Manchester United have agreed a £40million fee for Alejandro Garnacho, Daily Mail Sport understands.
The switch will also include a 10 per cent sell-on fee.
Both clubs had been locked in negotiations over the deal this summer after the 21-year-old was told by Ruben Amorim to leave at the end of last season.
There had been a gap in valuation - with United said to have been holding out for around £50m - but a compromise has been reached. Garnacho is now expected to head to London to undergo his medical checks as soon as tomorrow.
The forward is set to sign a lucrative seven-year deal at Stamford Bridge.
