Barcelona are preparing their offer for Lautaro Martinez, Inter Milan's Argentine forward who they want to sign in the summer.
According to some reports, the Catalan club have already offered around 70 million euros for the striker in addition to two players.
The two players who would enter into the deal are Arturo Vidal, a long-term Inter target, and right-back Nelson Semedo.
Lautaro's contract has a curious clause: between July 1 and July 15, he can leave the club at a cost of 111 million euros if a club is willing to stump up the full amount.
He would earn around seven million euros annually at Camp Nou, almost double what he currently receives at the Italian side.
Real Madrid are also keen on Lautaro, who Barça see as the long-term replacement for Luis Suarez, who turned 33 in January and is currently sidelined with a knee injury.
