Stoke City reportedly want to sign Brazilian striker Luan, but must first offload one of their current attacking players.
The Gremio ace has been linked with a move to the Premier League already this summer, having reportedly attracted interest from Liverpool.
According to The Sun it is Stoke who are at the front of the queue, however, with representatives of the 24-year-old holding talks with Stoke chiefs earlier this week.
It is claimed that the Potters can only make a bid if they first sell one of Xherdan Shaqiri or Marko Arnautovic, both of whom have been tipped to move on in the coming weeks.
Luan has netted 53 goals in 182 appearances for Gremio and, despite having just one year to run on his deal, would likely cost around £18m.
