The 24-year-old has netted 13 times in 26 appearances for the Imortal Tricolor this season. Primarily a second striker, the twice-capped Brazilian recently scored a brace in the first leg of the Copa Libertadores semi-final at Barcelona SC in Colombia. It leaves Gremio strong favourites to meet the winner of the all-Argentinean semi-final between Lanus and River Plate.
As a youngster, Luan flirted with a career in futsal but signed for Catanduvense in 2013 instead. Gremio stepped in during the same year and is hot favourite to be the next Brazilian sensation in European football.
Spartak Moscow saw a $22m bid rejected in the summer and Gremio are expected to cash in next summer.
However, the Premier League giants believe they can tempt Gremio in January provided there is an immediate loan-back deal through to the end of the Serie A campaign.
A member of Brazil’s 2016 Olympic Gold medal winning squad, Luan has been reportedly watched by Liverpool since August 2017.
Arsenal, set to lose Alexis Sanchez, 28, next summer see the Gremio striker as the ideal replacement for the Chilean and a signing to keep the Emirates onside during Arsène Wenger’s final season at the club.
