Chelsea defender Andreas Christensen was undergoing the second part of his Barcelona medical yesterday.
Christensen, 25, passed the first phase of his medical last week, reports Sport.
His agent will arrive in Barcelona between now and Thursday to formally complete the Bosman agreement.
Christensen’s talks with Chelsea broke down earlier this season, opening the door for Barca to swoop.
Bayern Munich had also been courting the Dane’s signature, but Xavi and Co have won the race after upping their offer last week.
Premier League teams were also interested, although Christensen reportedly snubbed them out of respect for Chelsea.
