The former Manchester United defender knows Rooney from his time at Old Trafford and believes Rooney is ‘simply unstoppable’.
“When he is focused he is simply unstoppable,” explained Pique.
“I have never seen a player as powerful as Rooney – the way he goes past people, the intensity of his play, the runs he makes from the first minute to last and the shot that he has. World class.
“Perhaps he does not get the credit he deserves because he should score more goals, but he offers so much.”
