Arsenal will reportedly demand at least £30m for wantaway striker Alexis Sanchez if a rival club bids for him in January.
Manchester City have been tipped to launch another offer for the Chile international when the transfer window reopens but, according to The Sun, the Gunners are unwilling to let him leave on the cheap.
Sanchez has just six months left on his current Arsenal contract and is said to be desperate to leave the Emirates after being omitted from their League Cup clash with Norwich City in midweek.
City boss Pep Guardiola is reportedly willing to offer £20m to bring the player to Manchester, but Arsenal are expected to hold out for more.
Sanchez, who joined Arsenal from Barcelona in 2014, was among the goalscorers as Arsene Wenger's side thrashed Everton 5-2 at Goodison Park over the weekend.
