The Brazilian winger could see his time with the La Liga champions come to an end after just one season
Barcelona and Borussia Dortmund are negotiating the transfer of Malcom, which would see the Bundesliga club pay €42 million (£38m/$47m) for the Brazilian winger, sources have told Goal.
Malcom has an €180m (£160m/$200m) termination clause in his current contract with the Liga champions, but Barca would accept his departure in exchange for €1m more than the €41m they spent to sign him from Ligue 1 side Bordeaux.
At the time, it appeared Malcom would be heading to Roma, with the Serie A club having agreed a fee with Bordeaux, only for Barca to swoop in at the last minute to land the winger.
But after a bright 2017-18 season with Bordeaux in which he scored 12 goals and added seven assists, Malcom struggled for playing time at Barca, managing 15 appearances for the club and just six starts in La Liga.
Without opportunities during the 2018-2019 season, Malcom was a serious candidate to leave Barca this summer.
