The 16-year-old, who was an integral part of the Black Starlets participation at the 2017 Fifa U-17 World Cup in India, claims that an initial enquiry over a possible move has been lodged but he is unaware of the details of the negotiations between his parent club Cheetah FC and Barcelona.
"It was sad Mali eliminated us from the tournament but we will hope for the best in the future. I have received contacts from Barcelona as well as many offers from other Spanish clubs," Toku told Metro FM.
"They want to sign me but I can't say anything about it now. I hope for the best," he added.
"I'm a fan of Asante Kotoko and believes they will win the FA Cup on Sunday against Hearts of Oak in Tamale. I predict a 2-0 win for Kotoko to win their first trophy this season," he said.
If the negotiations end successfully, Toku will become the first Ghanaian to represent the Catalan club.
