The perpetrators cut off the footballer’s legs in an attack yesterday morning, leaving just the tops of his ankles and a football attached to his magic left foot on the base of the sculpture.
It was the second time in less than a year that the work of art in the Argentine capital Buenos Aires had been vandalised.

“The people that are responsible for this and other negative things directed towards this person should know that our island was recently voted the world’s leading island destination not just for the beautiful sea that surrounds us or for our marvellous gastronomy or even the warm Madeiran welcome.
“It was in part thanks to this great Madeiran figure that honours his origins.”
Dubbing the vandals “frustrated savages” and saying they deserved to be sent to Syria in an attack in which she appeared at times to be overwhelmed by her own anger, she added:…
