The 29-year-old’s move from Romanian club Dinamo Bucharest was made official by his previous club via a statement released on Monday night.
"FC Dinamo Bucharest and PFC Ludogorets Razgrad have reached an agreement today for the definitive transfer of May Mahlangu to the Bulgarian champions," the statement read.
"Transferring to the club in Stefan cel Mare two years ago, May Mahlangu played 72 matches and scored three goals for Dinamo in all competitions.
"FC Dinamo Bucharest thanks May Mahlangu for his efforts in the white-red jersey and wishes him a lot of success with his new team."
Mahlangu, who has two goals in 18 games for Bafana Bafana and last featured for the national team in a 1-1 friendly draw against Mozambique in November 2016, says he’s elated with his move as he targets a successful spell in Bulgaria.
“I’m happy to come to a team like Ludogorets,” Mahlangu told his new club’s website. “I hope to achieve more success in the Bulgarian championship and the European competitions.”
Ludogorets becomes the sixth European club of the midfielder’s career, having previously turned out for Helsingborg and IFK Gothenburg in Sweden, Belgian side St Truiden, Konyaspor in Turkey and previous club Dinamo, with whom he won the Copa Ligii.
Mahlangu’s most successful spell was in Sweden, where his five years at Helsingborg produced one league title as well as two Swedish Cup and two Swedish Super Cup victories, with Mahlangu being voted Player of the Year in 2011.
New club Ludogorets have won the Bulgarian League for the last seven years in succession, and after falling short in the qualifiers for this year’s UEFA Champions League, are now involved in the UEFA Cup qualifiers, where they face Georgia’s Torpedo Kutaisi in the first leg of their play-off on Thursday.
They last featured in the group stages of the UEFA Champions League in the 2016/17 season, where they finished third in their group behind Arsenal and Paris Saint-Germain.
Ludogorets currently sit third in their 14-team domestic league with 10 points from their first five games.
