T-Mobile CEO John Legere is a candidate to become new CEO of WeWork

WeWork has spoken to T-Mobile CEO John Legere about possibly taking over the embattled coworking company, sources told CNBC's David Faber on Monday.

The Wall Street Journal first reported that the talks had taken place.

Shares of T-Mobile slid 3% on the news.

WeWork is conducting a search for a CEO and Legere is among several candidates being considered, Faber reported. The search is ongoing and no decision has been made, sources said. A source close to SoftBank confirmed Legere is one of many candidates being considered for the role, but he's not the leading candidate.

Representatives from T-Mobile and WeWork were not immediately available for comment. SoftBank representatives declined to comment.

WeWork has been searching for a new CEO following the departure of Adam Neumann, a co-founder, in September. Co-CEOs Artie Minson and Sebastian Gunningham took over after Neumann exited the company.

T-Mobile and WeWork have leadership in place that runs in similar circles. SoftBank, which took control of WeWork last month, is a majority owner of Sprint and played a role in installing Sprint CEO Marcelo Claure. Claure, who was recently named WeWork's executive chairman, helped orchestrate the $26 billion merger with T-Mobile, which is widely expected to be approved.

Legere is expected to step down as T-Mobile's CEO once the deal with Sprint is complete. Faber reported in July that T-Mobile President and COO Mike Sievert is expected to take over as CEO once the deal closes.
