Argentine Marcelo Bielsa has resigned as the Lazio manager just two days after taking up the job at the Serie A club.

The 60-year-old was officially due to start in his new post on Saturday having been appointed as Stefano Pioli’s replacement at the Stadio Olimpico on Wednesday.

However he opted out without any clear explanation of his decision, what could be related to his decision at the start of the 2015/16 season when he resigned as the Marseille head coach after just one match in the Ligue 1.

The club issued an official statement confirming the development, stating it is in violation of the agreement between them and the coach.

“We note with amazement the resignation of Mr. Marcelo Bielsa … in a clear violation of the commitments undertaken in the agreements signed last week,” Lazio said in the statement released on Friday.

The club is considering taking legal action against the former Argentina manager, and have appointed former striker Simone Inzaghi as his replacement.
