SoftBank Group Corp. is tapping Marcelo Claure to help turn around WeWork after ousting co-founder and Chief Executive Officer Adam Neumann from the corner office last week.

Masayoshi Son, the head of SoftBank, WeWork's largest investor, has asked the former chief executive officer of Sprint Corp. to take a more hands-on role helping oversee a cleanup of the office rental company from his position at SoftBank, according to sources familiar with the matter who asked to not be identified because the matter isn't public.

No decision has been made on his exact role, the sources said.
