The 17-year-old put in an impressive display in Barcelona's 5-1 victory over Ferencvaros in the Champions League on Tuesday night, scoring their second. However, the aftermath of the victory was soured by the paper's description of the Guinea-Bissau-born Spain international.
The paper's match report said: "Ansu in full flight has something of a gazelle about him, of a very young, black street seller that you suddenly see running along Paseo de Gracia when someone shouting 'water, water' (to warn other street sellers) announced that the local police have arrived.
"Now this kind of thing does not happen, because, for Ada Colau (the left-wing mayor of Barcelona), the criminals are the police and not the street sellers, who no longer have to run away. It is also true that without tourists, business is rather weak."
ABC is known in Spain as a newspaper that favours right-wing political parties and is an advocate of their policies.
The author, Salvador Sostres, issued a public apology on the ABC website on Thursday morning. He said: "As I attempted to highlight the beauty of Ansu's movement, and his class as a young player, some expressions were interpreted as racial discrimination.
"That could not be further from my intentions, or opinions, which are very favourable towards the player, as I have always expressed in my match reports since he made his debut.
"I deeply apologise for the misunderstanding and to those who may have been offended."

The report received widespread condemnation on social media, with Barcelona forward Antoine Griezmann tweeting: "Ansu is an exceptional boy who deserves respect like any other human being. No to racism and no to bad manners."
Former England and Barca forward Gary Lineker retweeted Griezmann's thoughts and said that the report felt like "stepping back 50 years."
Barcelona mayor Ada Colau also demanded a retraction from the newspaper and tweeted "All my support to Ansu Fati and to all the young, anonymous people who fall under this characterisation or stigma due to the colour of their skin."
