Rivaldo believes Haaland has the qualities to potentially reach the level of his former Brazil team-mate Ronaldo, who is widely considered as one of the best strikers of all-time.
The Norway international announced himself to the watching world when he scored eight goals for Red Bull Salzburg in the Champions League group stage, becoming the first teenager in the history of the competition to score in five consecutive appearances.
The 19-year-old joined Dortmund in January and has hit the ground running, having scored 13 goals in his first twelve games for the Black and Yellows.
Rivaldo believes the former Molde FK forward is showing shades of Ronaldo when he was introduced to European football during the mid-90s and has tipped Haaland to shine in La Liga in the near future.
"He is already a great player, but at 19 he could be even better in the future and become one of the best attackers in the world," the former AC Milan wrote for Betfair.
"He has a lot of personality, plays without fear and looks very calm on the pitch, so he is a world-class player that still has a lot to learn and it's normal that so many clubs are chasing him.”
"Some people are already comparing Haaland's style to Ronaldo Nazario and there might be some similarities as Haaland, as he's quick, fearless and scores a lot, but it's too early to start thinking he will be Ronaldo's successor.”
"Ronaldo won two World Cups and participated in four. He also dazzled the world with his runs and goals, so we need time to see if Haaland can reach Ronaldo's level. But Haaland does seem to have the qualities to at least get close to my brilliant team-mate.”
"Real Madrid seems to be Haaland's preferred destination in the summer and he is showing enough quality to prosper in Spanish football.”
“His ruthlessness in front of goal is putting him in a privileged situation and Barcelona could be a good alternative option for him. He will be a great signing for the club that manages to complete his transfer.”
