Oldham Athletic have signed Tottenham Hotspur midfielder Jamie Bowden on a season loan and have also recruited midfielder Ousseynou Cisse, goalkeeper Danny Rogers and striker Jacob Blyth.
Cisse, 30, and Rogers, 27, have both joined on one-year contracts.
Cisse has signed after a season with Oldham's fellow League Two side Leyton Orient and Rogers was most recently with Scottish side Kilmarnock.
Blyth, 28, has agreed a short-term deal after a trial spell.
Bowden, 20, has represented England and the Republic of Ireland at youth level but is yet to play a first-team game.
Curle said: "Since he came on Monday morning he's trained with us as a group and we can see why he's come with great references and why his club rate him so highly.
