It is highly doubtful many people outside of Paraguay had heard of Celeste Amarilla before her vile diatribe about Kylian Mbappe.Her leech-like behaviour has granted her 15 minutes of infamy, but it requires being called out as exactly that — a blood-sucking act that feeds off the vibrant life force of another. The leech attaches itself to the host without invitation. The leech takes without giving.As what appears to have been a manoeuvre of self-promotion, this is as cynical as it gets. Mbappe is a global superstar at the top of his game during the biggest global event happening. According to Google Trends, searches for Amarilla’s name rose by more than 5,000 per cent after she published an obscene attack on Mbappe. By choosing such a well-known target for her ultra-offensive bait, Amarilla would surely have been aware that it was likely to cause a stir beyond her own borders.Unfortunately for Mbappe, whose build-up to the World Cup quarter-final would be far more serene without this, he has been forced to attend to it — whether he wanted to speak out or not, it immediately became a viral story and a lens through which people would regard the France striker this week.When something deeply negative swirls around you, not of your own making, it can be a complicated dilemma to establish whether or not to tackle it publicly. Is it more powerful to rise above, to ignore, to cut off the supply of oxygen and attention? Or is it more powerful to engage and use a strong voice as an antidote to the kind of toxicity Amarilla brought into the public domain? Ultimately it has to be a personal decision. Mbappe made the decision to act.
