The Portuguese international beat Pique's Barca teammate Lionel Messi to the award last month, but the centre-back insists that he was glad to see his former Manchester United colleague triumph.
Pique told Jot Down: "He's got a reputation for being a tough guy, being above it all, so it was good that he had that reaction. He really wanted it, he'd suffered for it and he got it. I like that.
"I've haven't talked to him recently. I've changed my number a few times, just as he will have I guess, but if I've always got something good to say about him it's because I like him.
"People base their opinion on gestures or comments without really knowing anything. I should say that from what I've seen recently he's changed a bit, but personally I like the guy - he helped me a lot when I arrived at Manchester United."
Barca are currently second in La Liga.
