Barcelona have reportedly stepped up their interest in Lautaro Martinez by offering Inter Milan up to six players to choose from as part of the deal.
The La Liga leaders are expected to go all out to land their top target, who has found the back of the net 16 times in 31 appearances in all competitions this season.
Martinez has a €111m (£97.2m) release clause in his current deal at San Siro and is also believed to be on the radar of Manchester United, Real Madrid and Paris Saint-Germain.
In a bid to see off competition from other clubs, Spanish outlet Sport claims that Barca are willing to offload a couple of players to Inter, on top of paying £52.5m.
Arturo Vidal, Samuel Umtiti, Nelson Semedo, Junior Firpo, Rafinha and Jean-Clair Todibo are the players they are supposedly prepared to offer in order to strike a deal.
Barca vice-president Jordi Cardoner admitted last week that the club will be looking to swap, rather than buy players outright, during this summer's transfer window.
