One in, one out for Ross County
Former England manager Sven-Goran Eriksson has been appointed technical director of Al Nasr in the United Arab Emirates.
Eriksson, 64, was presented by his new employers at a press conference at the club's Al-Maktoum Stadium on Monday evening.
The move comes just days after the Swede turned down a job on the coaching staff at German second division side 1860 Munich.
Al-Nasr will be Eriksson's 16th coaching job and follows recent spells in charge of the Ivory Coast national team and Thai club side Tero Sasana.
However, Eriksson denied the move was driven by money, insisting his reasons for taking the job were purely footballing ones.
"I can promise you the jobs in Ivory Coast, Thailand and here were not for money - absolutely not," he said.
"I don't complain about the salary - I'm happy about that - but it's not for money. It's for the love of football and to see new parts of the world."
Al Nasr, who are coached by former Italy goalkeeper Walter Zenga, currently lie fifth in the UAE Pro League.
Wohlfarth was most recently at Wehen Wiesbaden in the third tier of German football and previously played for Bayern Munich reserves in the same division.
County revealed former Hamilton and St Mirren player Corcoran had "left with immediate effect". The 32-year-old made four appearances in August before being hit by a groin injury and has only played once since.
Manager Derek Adams previously brought in Ivan Sproule and Evangelos Ikonomou, who made their debuts in Saturday's 4-1 win at St Mirren, and is awaiting a work permit for Canada international Andre Hainault.
Adams told the club's official website: "Whilst we knew we had to add to the squad, it was important that it wasn't just numbers - anyone we bring in has to add something to what is a great group of players already at the club.
"We've had to cast the net far and wide to achieve that whilst working within our budget but with Ivan, Evan and now Steffen I think we've proved that it is certainly possible.
"At the same time it has been confirmed that Mark Corcoran has left the Club with immediate effect. All at Ross County thank Mark for his contribution during his time at the Club and wish him well in his future career."
