Barcelona officials are understood to have met with representatives from Inter to discuss the futures of both Arturo Vidal and Lautaro Martínez.
Inter are keen on Vidal to bolster their midfield options, while Barcelona have identified Martínez as one of their top targets to replace Luis Suárez in the near future.
For Barcelona, the problem is that Martínez has a €111m release clause. They do not want to pay such a high price, but according to Mundo Deportivo, they are willing to offer Vidal in a player-plus-cash deal.
Given he has started just three La Liga games this season, Barcelona would be open to letting Vidal go. Inter boss Antonio Conte is ready to offer him the game time he is looking for, and La Blaugrana want to use that to their advantage.
The group of Barcelona officials, which is thought to have included both Eric Abidal and Ramón Planes, are not actively looking to sell Vidal, but they would not hesitate to throw him into the mix if Inter indicated a willingness to part with Martínez.
However, Inter are not keen on losing the 22-year-old, who has fired 13 goals in 20 appearances this season. They want to tie him down to a new contract to put an end to the speculation, with Conte eager to avoid any off-field distractions during the season.
As noted by Sport, Martínez's representatives have already met with Inter to discuss the possibility of a new contract, but his agents have arrived in Milan at the same time as the Barcelona group to allow them to discuss a possible transfer.
It is thought that his agents could again meet with Barcelona in the coming days, likely after the Champions League clash between the two sides on Tuesday, to see whether a possible swap deal involving Vidal would be a possibility.
Sport also add that Ivan Rakitić's name has been suggested as part of any deal, but Barcelona's €30m valuation of the midfielder has effectively brought that speculation to an abrupt end as Inter cannot afford to meet those demands.
What is certain is that the two clubs will remain in contact over the coming weeks, with both teams seemingly keen on striking a deal with the other.
