Serie A giants ​Inter Milan turned their attention to Racing Club and the Argentina international forward Lautaro Martinez after missing out on Barcelona-bound starlet Arthur, Italian outlet Calciomercato have revealed. 

Inter were among a number of clubs trying to sign the Gremio midfielder, but turned their attention to compatriot Lautaro when it became evident that he would instead be joining ​La Liga leaders Barcelona.  

The Catalan club confirmed on Sunday that they have agreed a purchase option - which can be exercised from July 2018 - with Gremio for the 21-year-old in a deal worth €30m plus €9m in various add-ons.

"​FC Barcelona and the Brazilian club Gremio de Porto Alegre have reached an agreement on a purchase option for the player Arthur Henrique Ramos de Oliveira Melo, whereas FC Barcelona may exercise this right on the player's federative rights during July of 2018," a statement from the club read.

Inter-bound Lautaro, on the other hand, is rumoured to be the costing the clu​b €20m. The Argentine international, who has scored a total of 18 goals in his 40 appearances for Racing, is expected to sign a five-year deal with the ​Serie A giants in the summer. 

While a deal has not been officially announced by either club, Racing Club President Victor Blanco recently confirmed that Lautaro’s move to Inter is '90% complete'. 

"It's 90 per cent complete. There is already a pre-agreement signed with Inter. He will leave for a sum which we believe corresponds to his value. I can see him going to the World Cup, even if it's ultimately up to [Argentina coach Jorge] Sampaoli to decide," he claimed on Radio Rivadavia.
