Alf-Inge Haaland and Raiola were caught on film at El Prat Airport outside Barcelona.
According to the Barcelona-based sports magazines Mundo Deportivo and Sport, the duo was then picked up by "Barca" new chairman Joan Laporta.
According to the newspapers, Dortmund striker Haaland will be Barcelona's first choice in this summer's transfer window.
The acknowledged good relationship between Raiola and Laporta should contribute to the Catalans' optimism to connect with the Norwegian.
Will cost SEK 1.8 billion
Haaland is under contract until 2024 with the German club Dortmund.
But in the agreement, there must be a clause that allows him to leave the club for a certain price in the summer of 2022. According to the newspaper Sport, Dortmund must have put a price tag of SEK 1.8 billion on the Norwegian.
Something that speaks against the deal is that Barcelona has debts of around the equivalent of SEK 12 billion.
Dortmund does not want to sell
Dortmund's sports director Michael Zorc tells German Sky that the club does not want to sell Haaland this summer.
- Yesterday I talked to Mino Raiola.
We were very clear about what we want, says Zorc.
According to Mundo Deportivo, Alf-Inge Haaland and Raiola are also on their way to the Spanish capital for talks with Real Madrid.
