27 year-old Abidal, who will make the move from Ligue 1 winners Lyon provided he passes the obligatory medical, has played 24 times for France and has also won the French Ligue 1 title 3 years in a row since joining Lyon from Lille in 2004.
He will team up with Thierry Henry and Ivory Coast midfielder Touré Yaya as Barca continue to strengthen for next season’s campaign.
