Dundee United have signed Falkirk midfielder Mark Millar on a pre-contract agreement, the club has announced.
United say the 24-year-old has signed a three-year contract, which will come into effect when his Falkirk deal expires at the end of June.
The central midfielder joins Ross County winger Michael Gardyne in signing a pre-contract at Tannadice.
United manager Peter Houston said: "In my opinion we have now captured the two best players in Division One with Mark Millar and Michael Gardyne.
"Mark has shown the right attitude and mentality in leaving Celtic to go down a division in order to kick-start his career.
"That decision has been vindicated for him in now signing this pre-contract agreement which will enable him to showcase his talent at SPL and European level.
"He is a different style of player to those we have here already and the way he plays the game will make him a fans' favourite here at Tannadice once he arrives."
