Derby County have completed the loan signing of Manchester City's defender Danny Mills, subject to FA confirmation.If it goes through without a problem the 30-year-old former England international will move to Pride Park until the end of the season. Derby boss Paul Jewell told the club's website: 'Danny is joining us on loan until the end of the season and his experience and versatility will be invaluable to us. 'Danny has now been playing at the highest level for a long time now, including a World Cup for England, so nothing will faze him. 'He is a hardened battler and will be great in the dressing room.' The right-back has spent the last few months on loan at one of his former clubs Charlton. However, the move ended on a sour note as Mills was sent off in a 1-1 draw with Hull at The Valley on December 22, incurring a three-match ban. But with the suspension now served, Mills will be available for selection for Derby's FA Cup third-round tie against Sheffield Wednesday at Pride Park if the deal can be completed in time. Agent Neil Featherby said: 'It's a great chance for Danny to play in the Premier League again. 'Danny has always been the type of player who relishes a challenge. If anything, he thrives on it. 'With the position Derby are in it at the moment, and with Paul Jewell needing players who are prepared to roll their sleeves up and dig in, then they won't get anyone better than Danny.'
