The change of U in the last minute of Malcom in a move to Rome in favor of joining Barcelona was an act of "revenge" according to his agent.
Leonardo Cornacini was unhappy with Rome for the way they handled another agreement earlier in the window, stating: "Rome behaved badly to us."
As a result, Malcom broke an agreement to join Rome just before boarding a plane to Italy after a late bid from Barcelona for the Brazilian striker.

The 21-year-old joined Barcelona in July for a fee of £ 45 million, even though Roma announced that they had agreed terms for the player with Bordeaux.
"The truth is that we decided not to go to Rome because they behaved badly to us," Cornacini told Tuttomercatoweb.
"I was working on an agreement for (Daniel) Fuzato, which is another of my clients, but Rome closed it with another agent, although it's worth mentioning that I have nothing against him." In summary, it was revenge.
The Malcolm agent claims they made a U-turn in their move to Rome for "revenge"
I'm sorry to say, but that's what it was. Rome behaved badly to us, 10 days before with the deal with Fuzato, so we acted the same way with them.
"Given the attitude shown towards us, I decided, together with Malcom, that the best destination was not Giallorossi's.
"And then again, in the same deal for Malcom, Monchi had involved other intermediaries, but today, Malcom is happy to be a new signing for Barcelona."

The Brazilian striker will face stiff competition for a place in the starting lineup after Ousmane Dembele chose to stay at the club.
However, Barcelona had a successful cleanup, following the departures of Yerry Mina, Andrés Gomes, Paulinho and Lucas Digne.
The Barcelona season starts with the Spanish Super Cup against Sevilla on Sunday, before the League returns next weekend.
