"Villa is here to make a difference, it is a pleasure to have Villa in any team," said Xavi. "This is fantastic news. He is a great player and a great goal scorer.
"This is a ten out of ten signing by Barcelona.
"You could say he has similar characteristics to Samuel Eto'o."
On Arsenal captain Cesc Fabregas, Xavi added: "Villa and Cesc, if he comes too, are welcome and will continue the football that characterizes us and they'll help us achieve further success."
