The 20-year-old Brazilian has agreed initial terms with Barca and the Catalans are set to make a concrete bid for the youngster.
Keirrison has admitted that he would be keen on a move to Barcelona.
“I would really like to play alongside Lionel Messi,” Keirrison told Sport. “He is the best player in the world.
“Since I was very young I have wanted to play in a country and with a great club and, while I have nothing against any others, I have always identified with Barcelona.
“I have seen a lot of games when Romario and Ronaldo were there and that made me dream that one day I would play in a great club like Barcelona.”
Keirrison has also been linked with several other clubs, including Real Madrid and Liverpool.
