Derby County have completed the signing of midfield pair Benny Feilhaber and Mika Vayrynen - though neither player is available for tonight's match at Manchester City.
Feilhaber, an American international who plays for German club Hamburg, needs international clearance, which can take up to a week.
Derby have been granted a work permit for the 22-year-old who could cost around £1m.
Vayrynen underwent a medical at the weekend and talks over personal terms are ongoing.
A deal to sign the 25-year-old has been agreed with his club, PSV Eindhoven.
