One of Northampton Town's young stars, Michael Jacobs, is joining nPower Championship side Derby County for an undisclosed fee.
The 20 year old midfielder, a product of Northampton's Centre of Excellence and youth team, rejected a substantially improved contract offer to stay at Sixfields earlier this year.
Jacobs made his debut for the Cobblers in the Johnstone's Paints Trophy in November 2009 against the MK Dons, just six days after his 18th birthday.
In all, he made 100 senior appearances for Northampton, scoring 15 goals.
'This news won't come as a surprise to anybody after Michael turned his contract down', said Northampton manager Aidy Boothroyd.
'We respect his wish to make the move and we wish him well in his future career. Now we move on and this gives us the opportunity to strengthen the squad further ahead of next season'.
Cobblers' chairman David Cardoza added, 'Although a few clubs had expressed an interest in Michael, Derby were the only club to actually submit an offer, and we have negotiated hard with them to get the best deal possible for the club.
'Once Michael had spoken to Derby, agreed terms, passed his medical and signed a contract, they became his destination. It was then a case of either going to a tribunal or agreeing a deal with Derby, and we reached a deal that we felt was in the best interests of the club'.
