Galatasaray's interest in Martinelli comes after they failed to agree a deal with AC Milan for Portuguese forward Rafael Leão. The Turkish club is now considering Martinelli as an alternative. Martinelli's situation at Arsenal has been complicated by the arrival of Greek forward Christos Tzolis from Club Brugge, who signed for around £200 million. The Arsenal hierarchy is only willing to release Martinelli if they can secure a replacement for the Brazilian forward. Several names are being monitored, including Kenan Yildiz, Julián Álvarez, Iliman Ndiaye and Eli Junior Kroupi. Martinelli's contract situation increases the likelihood of a transfer this window, with Arsenal having the option to extend his deal by a further season. If Martinelli is sold, the Brazilian forward could represent a significant deal for Arsenal, with the club reportedly hoping to receive more than the £35 million they received for Alex Oxlade-Chamberlain in 2017, a record sale for the Gunners.
