Barcelona have welcomed Tottenham's approach for Rafinha.
Spurs have asked Barca about a price for Rafinha, who is up for sale after a successful six month loan with Inter Milan.
Inter had an option to sign him permanently for €35m, but have passed on it.
Sport says Spurs have now come forward and Barca are keen to do business as they push for Christian Eriksen to be included in negotiations.
Barca see the Dane as an alternative to Atletico Madrid attacker Antoine Griezmann.
