West Ham have signed Said Benrahma from Brentford, initially on loan.
A deal was thought to have been reached earlier on Friday, but reports suggest that a problem with the 25-year-old Algerian's medical led to a renegotiation.
The deal has been restructured with a £4 million fee believed to be paid for a season-long loan, ahead of a £25 million price for a permanent move at the end of the term.
