After three trialists were training witht he Brewers during pre-season, Hasselbaink has confirmed that two have left.
Zeli Ismail was one of three trialists with the club who has joined Burton Albion on a six month loan deal from Wolverhampton Wanderers.
Tom Flanagan, a defender currently contracted at MK Dons has also been on trial with the Albion and he featured against Leicester City and Derby County at the Pirelli Stadium during pre season.
The final trialist was winger Bruno Andrade who spent last season and the season before on loan at League Two Stevenage from Queens Park Rangers. The tricky winger featured numerous times for Hasselbaink's men during pre-season but he has failed to make an impact.
Hasselbaink told burtonalbionfc.co.uk "Tom Flanagan has gone back to MK Dons, that signing won’t be happening.
"Bruno Andrade has also left the club after his trial."
