Alexis Sanchez has scored eight goals in 21 appearances for Arsenal this season

Forward Alexis Sanchez will leave Arsenal in January if a suitable offer arrives and a replacement is secured.

It is understood the Gunners hierarchy have privately accepted for some weeks that Sanchez is likely to depart after three and a half years at the club.

However, Arsenal are reluctant to sell without replacing the Chilean and their first choice is Bordeaux’s 20-year-old Brazilian forward Malcom.

Manchester City is 29-year-old Sanchez’s most probable destination.

Conversations have been held between the clubs but there is as yet no agreement on a fee.

Arsenal are thought to have asked for up to £35m, with Premier League leaders City initially suggesting they would pay around £20m. Sources anticipate a compromise of between £25m and £30m.

It is also widely reported that Manchester United will rival City’s interest and have already made a bid.
