Rotherham are unlikely to make any more signings before the end of the month, according to manager Steve Evans.
Derby captain Richard Keogh has agreed a new three-year contract with the Sky Bet Championship outfit.
David Moyes has promised Manchester United fans that Wayne Rooney will not be last big-name signing at Manchester United this year.
Rooney finally put pen to paper on a new five-and-a-half year contract worth £300,000 a week on Friday evening.
The news comes a month after Moyes smashed the club's transfer record to sign Juan Mata from Chelsea for £37.1million.
And after experiencing a summer of disappointment in the transfer window last year, the United manager has vowed to make even more key signings this summer.
"I want to bring more Wayne Rooneys to Manchester United," Moyes told MUTV after the club announced Rooney had signed his new contract.
"We're having to build again and start again.
"Part of the rebuilding (process) is making sure that you keep the players you really want to keep.
"We are looking to bring the best players in the world to the club.
"Wayne Rooney is one of the best in the world.
"I will be looking to make more signings in the summer and hopefully add to the quality we already have got.
"It (the signing) tells the fans it'll get better - and it will. I've had great support from the owners and the board - and it won't be the last, that's for sure."
Of all the leading figures in the world of football, few know Rooney better than Moyes.
The Scot handed Rooney his Everton debut in 2002 when the striker was just 16 years old.
Chelsea's interest in the player, and the way in which the pair fell out following Rooney's exit from Everton, led to speculation that the Merseysider would leave United this summer after a 10-year spell at the club.
But United dug their heels in and Moyes insisted he never contemplated the idea of letting Rooney leave.
"I am thrilled that we have got Wayne Rooney to stay," the United manager said.
"He has been fantastic. Everyone would want him in their team.
"There were clubs who did want him. There were clubs who would have wanted him (had he not signed a new deal) but there was never going to be a chance he was going to leave Manchester United, certainly not on my watch."
The striker has scored 11 goals during a season in which he has been hindered by injury.
When at his best, there is no questioning how important Rooney is to United, though.
The England forward has scored 208 goals in 430 appearances for the club and is viewed by many inside the club as the best man to replace the departing Nemanja Vidic as captain come the end of the season.
Rooney is 41 goals short of reaching Sir Bobby Charlton's record of 249 goals for United and Moyes feels the striker now has the opportunity to write himself into the club's folklore.
"Wayne is a great but he's got a real chance to improve and be a legend," Moyes added.
"He (Rooney) has matured. It's a bit like deja vu because I remember signing him as a 16-year-old.
"He's an overall team player. Look at the effort he puts in for the team.
"He needed to reinvent himself (last) summer and I think he did that. He came back and everyone saw the aggressive, tenacious, hungry, goal scoring Wayne Rooney again."
