Martin Allen has continued rebuilding Milton Keynes Dons' squad with the signings of Sean O'Hanlon and Drissa Diallo.
Both are central defenders and arrive after their contracts expired at Sheffield Wednesday and Swindon respectively.
33-year-old Diallo (pictured) brings a great deal of experience having also played for Burnley and Ipswich in England.
Unlike Diallo, former Everton youngster O'Hanlon will cost a fee - but as yet the two clubs have been unable to agree a deal and so the transfer will be set by a tribunal.
"Both players have a wealth of experience, both players are centre backs and I'm sure both players will be an asset to this club," Allen told the club's website.
