Semedo, 24, had just joined from Benfica when he got involved in one of the final episodes of the Brazil forward’s Camp Nou-career in July 2017 prior to his world-record €222 million exit to Paris Saint-Germain. The pair got into a heated argument during training in Miami and had to be pulled apart by team-mates, before Neymar stormed off.
“It was difficult, but they are the things that happen,” the Portuguese told Mundo Deportivo.
“We train everyday with a lot of enthusiasm. It happens in all teams.”
This pre-season has seen two other Brazilians make their mark with the La Liga champions.
Signings Arthur and Malcolm have already got on the score sheet for their new employers, the former in a 2-2 draw with Tottenham and the latter during a 4-2 defeat to Roma.
Semedo has been impressed with what he has seen so far.
He said: “They are fine. They have arrived scoring goals.
“I try to help them in any way I can with my language, which is Portuguese. We must help them in their adaptation.
“They improve day after day and they are assimilating into the concepts of the trainer [Ernesto Valverde].”
Semedo made 36 appearances for Barca last term.
The Giallorossi were hours away from signing the Brazilian last week and had even reached an agreement with French side Bordeaux when Barca swooped in with a bigger offer, landing the 21-year-old talent for €41 million.
Ahead of the International Champions Cup fixture at Texas’ AT&T Stadium, Roma defender Kostas Manolas said he had “never heard” of the Brazilian forward and the club’s social media account jokingly “muted” him from its timeline.
But the player saw the lighter side, saying to reporters after the game: “I don’t get involved with that sort of provocation.
“What’s important is what happens on the pitch. There’s no need to go over and over [what happened]. I am here, I’m a Barcelona player and I want to help. I hope to be able to make the supporters happy.”
Pressed for his thoughts on how social media savvy Roma have dealt with the transfer saga on Twitter, he added: “No, nothing [to say]. It’s just jokes. I’m not angry about it.”
The Blaugrana new boy had several good chances throughout the game, and gave Barca a deserved second-half lead after Rafinha and Stephan El Shaarawy had exchanged first-half goals.
However, as coach Ernesto Valverde rang the changes, ending the game with 10 B team players on the pitch, the Spanish champions fell apart.
Roma took full advantage and turned things around with late goals from Alessandro Florenzi, Bryan Cristante and Diego Perotti.
