Cristiano Ronaldo's sister hits out at Gerard Pique

Cristiano Ronaldo's sister Katia Aveiro has taken advantage of Barcelona's Clasico defeat to launch a barb at Gerard Pique.

While Leo Messi congratulated Cristiano, the Portuguese's sister hit out at the Barcelona defender by contrast. First she asked him about his famous 'Periscope'. 

"My question is if today Gerard Pique will make a Periscope. Everything started with you, no?" she wrote on Twitter. A message fired quite soon after the end of the Clasico. 

She recently came out in defence of her brother and her nephew when he was seen playing videogames instead of celebrating his father's goals.
