Arsenal have reportedly failed to reach an agreement with England winger Theo Walcott over a contract extension.
The 23-year-old, whose contract expires in 2013, is said to want to stay and is willing to continue negotiations.
However, various newspaper reports claim Arsenal will sell him before Friday's transfer deadline unless he signs an improved five-year deal worth £75,000 a week.
Walcott joined Arsenal from Southampton as a 16-year-old in 2006.
He started the home draw with Sunderland on the opening day of the season but was left on the bench for Sunday's draw at Stoke, eventually coming on after 72 minutes in the Gunners' second straight 0-0 draw.
