Arsenal will reportedly refuse to sell Pierre-Emerick Aubameyang in the final stages of the January transfer window unless a club submits an offer of £50m.
The 30-year-old, who has just served a three-match suspension for the Gunners, has scored 16 times in 26 appearances at club level during the 2019-20 campaign.
Barcelona have been strongly linked with a move for the Gabon international this month as his contract at the Emirates Stadium will expire at the end of next season.
The Spanish champions are believed to be in the market for a new forward having lost Luis Suarez for an extended period following a knee operation.
However, according to The Express, Arsenal are not prepared to allow Aubameyang to leave the club this month unless an offer of £50m is submitted.
The former Borussia Dortmund attacker, who has also been linked with Real Madrid, has scored 57 goals in 91 appearances for the Gunners since making the move in January 2018.
