New Delhi: India's second largest software services exporter Infosys, which is 'resistant' to outside talent, needs to open up to the idea of considering outsiders for top posts as it battles exit of top management executives, global brokerage firm CLSA said in a report.

"NR Narayana Murthy's return suggested that Infosys' leadership planning clearly didn't work out as expected. Ashok's exit has only exacerbated that issue.

"We believe Infosys needs to show greater openness to external candidates for senior roles, something which it has been highly resistant to," CLSA said.

Infosys declined to comment on the report. Murthy, returned from retirement as Executive Chairman in June to steer the faltering firm he co-founded in early 1980s.

Last week, the Bangalore-based firm's head of Americas and global manufacturing, Ashok Vemuri, stepped down from his role.

Vemuri was seen as a top contender for the CEO's post (along with B G Srinivas and V Balakrishnan) after term of the incumbent and co-founder S D Shibulal ends in 2015.

Besides, after Murthy's return, Infosys has seen its sales head Basab Pradhan as well as North America chief for financial services Sudhir Chaturvedi quit the company.
