Oldham Athletic have signed midfielder Brice Ntambwe and goalkeeper Laurence Bilboe on free transfers.
Both players have agreed one-year contracts, with options for a further season with the Latics.
Oldham have also brought in Arsenal's 19-year-old defender Harry Clarke on loan until 20 January.
Clarke has been with the Gunners since 2015 and played for their Under-21 side in Tuesday's English Football League Trophy victory at Crawley Town.
Ntambwe, 27, began his career at Birmingham City and appeared for Macclesfield in the season half of last term, playing 12 times for the Silkmen.
Oldham say former Rotherham and Havant & Waterlooville keeper Bilboe, 22, will "add competition".
