Rotherham have made Chelsea youngster John Swift their 12th summer signing, bringing him to New York on a season-long loan.
Swift, an England youth international, has made one appearance for the Blues' first team and will spend the entire 2014/15 campaign in South Yorkshire as the Millers enjoy life in the Championship.
The midfielder can operate in a central role or on either flank and his arrival marks the end of a lengthy chase by boss Steve Evans.
"It has taken many weeks to secure the signature of this young man and I suppose I could say my tenacity has paid off," Evans said.
"A number of fellow Championship clubs, as well as two European clubs, were keen to sign John but thankfully he has decided his immediate footballing future is at Rotherham United.
"John is another part of the jigsaw as we get ready to embrace Championship football. He, like every player in our squad, has an important part to play but he may not be the last player in the door before the start of the season next weekend."
