According to reports, formal talks between the two clubs began on Friday. This comes as Sesko is currently with the Slovenian national team, although he missed their recent match against Luxembourg.
It has been suggested that RB Leipzig asked the Slovenian Football Association to keep Sesko off the pitch during this international week, in order to protect him from injury while negotiations with Arsenal continue.
Arsenal is reportedly seeking to finalize a deal with RB Leipzig for around £60 million.
