Tottenham have confirmed they rejected a bid from Manchester United for England midfielder Michael Carrick.
Man Utd must up their bid to prise Carrick from Spurs
BBC Sport's Jonathan Legard exclusively revealed on Friday evening that Spurs had turned down a £10m offer for 24-year-old Carrick.
Then on Saturday a Spurs spokeswoman said: "We can confirm we have rejected a bid from Manchester United for Michael Carrick.
"Michael Carrick is a player we are not looking to sell."
Spurs are understood to have told United to double their offer for Carrick, who is part of England's squad at the World Cup.
However, it is thought an offer of £15m might seal a transfer for the midfielder, who Tottenham purchased for £2.75m from West Ham in August 2004.
Manchester United faxed their £10m bid to Spurs on Friday, but it was swiftly turned down.
Carrick's agent, David Giess, declined to comment when contacted by BBC Sport late on Friday.
United boss Sir Alex Ferguson wants Carrick as a replacement for Roy Keane who left the club last December.
But the timing of the offer may not have pleased England coach Sven-Goran Eriksson.
Eriksson is reported to be at loggerheads with Ferguson after declaring Wayne Rooney "injury free" and almost ready to return to action with England in Germany.
Rooney, 20, is still recovering from breaking a metatarsal in his right foot on 29 April and United do not want him to be risked too soon.
The England coach will want Carrick to concentrate fully on the World Cup rather than the speculation surrounding which club he will start next season with.
Manchester United have not commented about their bid for Carrick and it is unclear whether they will increase their offer.
