But Pique says Barcelona team-mate Messi is better overall than Ronaldo
Pique left Manchester United and joined Barcelona for second time in 2008
He says Sir Alex Ferguson was like a father to him in Manchester
Gerard Pique has claimed that his Barcelona team-mate Lionel Messi is so good that it is difficult to believe he is human.
Messi has won the FIFA Ballon d'Or four times - more times than anyone else - and if it wasn't for Cristiano Ronaldo he would have claimed the title two times more.
Pique, who played with Ronaldo at Manchester United and has lined up with Messi since 2008, believes both are exceptional but the Argentine is the world's best.
'I think that they are both amazing,' Pique told BT Sport. 'We are talking about two of the best players, not just in the world but the history of this sport.
'I always said that Messi has some talent that no one has. I mean, he has the ball and his speed controlling the ball. The ball doesn't go two metres far from his foot, it's always there. It's impossible to catch him, this talent I didn't see from anyone
'Cristiano Ronaldo is such a different player, they are very different. He is tall, strong, he's really complete. He can do anything. He can do goals with the head, free-kicks, penalties, take one on one.
'But for me it's like Messi is not human but Cristiano is the best of the humans.'

Two other individuals that Pique has a lot of respect for are Sir Alex Ferguson and Pep Guardiola.
Ferguson helped to nurture the defender and made him feel comfortable living in Manchester when he arrived from the Nou Camp in 2004 - a city that was alien to him after growing up in Barcelona.
He also got to know Guardiola very well due to the Spanish coach's reign as Barcelona manager from 2008 to 2012.
Pique described the early days of Guardiola's reign as 'really intense' while at Manchester United, Ferguson was similar to a godfather.
The Spain international was at United until 2008, before joining Barcelona via a loan spell at Real Zaragoza.
'Sir Alex Ferguson, when I was there I remember (Carlos) Queiroz was the guy who took training, he [Ferguson] was like more outside, controlling everything, taking a different position.'
Ferdinand interjected: 'Like the godfather?'
Pique said: 'Exactly. And Guardiola was like every day, he was there, but both of them you can see their careers. They are both fantastic.'
