Barcelona have two weeks to finalise a move for Ousmane Dembele, Borussia Dortmund chief executive Hans Joachim Watzke has indicated.
The identity of Barca's replacement for Neymar, who joined Paris Saint-Germain for a world-record fee of EUR222million earlier this month, is yet to be determined, with Dembele and Liverpool's Philippe Coutinho believed to be the Catalan giants' preferred targets.
Dortmund told the German stock exchange last week that they had rejected a EUR100m bid from Barca for Dembele, who only moved to Signal Iduna Park from Rennes in July 2016.
The 20-year-old French forward has been indefinitely excluded from selection contention after missing a training session without permission.
Liverpool's owners, meanwhile, released a statement on Friday insisting they will not consider any offers for Coutinho, an announcement that was swiftly followed by reports the Brazil international had submitted a transfer request.
It remains to be seen if Ernesto Valverde's Liga powerhouse will succeed in securing the services of either player before the transfer window shuts on August 31.
Watzke, though, may have sought to force Barca's hand with his latest remarks regarding Dembele.
"The time horizon is enough for two games," he told Kicker when asked for an update on the situation.
Dortmund are away to Wolfsburg in their opening game of the new Bundesliga season on Saturday, followed by a home match against Hertha Berlin a week later.
