Charl Langeveldt, the former South Africa fast bowler, will take over as Bangladesh's new fast-bowling coach. He will join the team full-time on a two-year contract.

The BCB has also appointed Daniel Vettori, the former New Zealand left-arm spinner, as Bangladesh's spin-bowling coach, on a short-term basis. Vettori will be with the team for 100 working days - which will include the tour of India later this year, and the T20 World Cup next year in Australia - and also conduct spin-bowling camps in Dhaka.

Langeveldt and Vettori replace Courtney Walsh and Sunil Joshi, whose contracts were not renewed following Bangladesh's eighth-place finish at the World Cup.

The BCB made these appointments during its board meeting on Saturday, where it also decided to renew the contracts of senior selectors Minhajul Abedin and Habibul Bashar, and extend the tenure of the white-ball batting consultant Neil McKenzie until next year's T20 World Cup.

The role of head coach remains vacant, with the BCB having spoken to a number of candidates since it parted ways with Steve Rhodes after the World Cup. "We spoke to some coaches, and Andy Flower is one of them," Nazmul Hassan, the BCB president, told ESPNcricinfo. "But nothing has been finalised. We are still talking to the coaches."

ESPNcricinfo has learned that Flower, who had initially shown interest, has declined the role due to personal reasons.

The future of fielding coach Ryan Cook could be in doubt, with the BCB displeased by Bangladesh's fielding during Friday's first ODI against Sri Lanka in Colombo. "After what happened yesterday, we have to ask the fielding coach what's wrong," Hassan said. "After that we will decide if we need a new fielding coach."

Langeveldt has previously held the role of bowling coach with South Africa (2015-2017) and Afghanistan (a short-term role in 2018). Vettori has vast experience of coaching at the franchise level, having served spells at Royal Challengers Bangalore, Middlesex, Brisbane Heat and Rajshahi Kings. He is also the current assistant coach of Birmingham Phoenix in The Hundred and head coach of Dublin Chiefs in the Euro T20 Slam.

"This is a team on the rise and there is so much experience and potential," Vettori said. "It will be a pleasure to work with the likes of Shakib Al Hasan, Mehidy Hasan Miraz, Taijul Islam and the other up and coming youngsters which I am looking forward to with a lot of interest.

"Spin bowling has been a traditional strength for Bangladesh. I hope to share my knowledge as a player and coach of the demands of modern day spin bowling in all versions of the game and help the bowlers make good intelligent decisions so that they can maximise their talents and skills."
