AFC Wimbledon boss Neal Ardley has drawn up a shortlist of seven summer transfer targets as he shapes his squad for a crack at promotion next season.
Those five departures, coupled with an increased playing budget for next term, means Ardley has money to spend in the transfer market.
Full-back Smith, in particular, was one of the highest earners at Kingsmeadow and his exit frees up funds for new signings.
Youngsters Tom Beere and Will Nightingale enjoyed breakthrough seasons and are expected to remain in the manager’s plans for next term.
Defender Ryan Sweeney, who was this week called up to the Republic of Ireland’s U18s squad , is also pushing for starts in the heart of the defence.
The 18-year-old, who joined the club's academy 10 years ago, will join Paul Doolin's squad for a training camp on May 30 before away fixtures against Luxembourg on June 2 and June 4.
Ardley has pulled out of the running to sign Jake Goodman following his release by Millwall after deciding the player’s form after breaking his foot was not worthy of a contract.
Question marks remain over the future of star striker Bayo Akinfenwa.
The Beast has a release clause in his contract, signed last summer, which dictated his deal needed to be reviewed if promotion to League One was not achieved in his first season.
Akinfenwa has been offered an improved contract by Ardley but is understood to be considering a move abroad.
