Busy Deadline Day For Scottish Clubs
Celtic and Rangers both got their men on transfer deadline day with the Hoops completing a double signing of Colin Kazim-Richards and Patrick Roberts while Michael O'Halloran finally moved to Ibrox.
Turkey international striker Kazim-Richards joined Celtic on a two-and-a-half year contract from Feyenoord while 18-year-old winger Roberts joins on an 18-month loan deal from Manchester City, six months after his £12million move from Fulham.
Nadir Ciftci departed on loan to Turkish side Eskisehirspor until the end of the season while 18-year-old attacking midfielder Aidan Nesbitt joined Partick Thistle on a similar deal, fresh from hitting a double in a 3-0 under-20s win over Rangers.
O'Halloran signed for Rangers until 2020 after the Ladbrokes Championship leaders succeeded with a third bid understood to be worth a potential £500,000.
Rangers also signed Mekhi McLeod from Wolves but the wide player will start off with the club's under-20s squad.
St Johnstone earlier released fringe player Liam Caddis and manager Tommy Wright did not bring in anyone else despite previously looking for a left winger. But chairman Steve Brown told the club's official website: £I'm satisfied with the transfer fee which reflects our full valuation of the player and we wish Michael all the best in the future.''
Saints could again bid to re-sign Danny Swanson after the midfielder left Hearts in a busy day of activity at Tynecastle.
Hearts had a bid accepted for Dundee United defender John Souttar and talks continued over a potential move to Middlesbrough for Jordan McGhee as the deadline approached.
Hearts earlier signed former Scotland midfielder Don Cowie after the 32-year-old was released by Wigan, and Robbie Neilson bagged his £"number one target'' in Nigerian forward Abiola Dauda, a 27-year-old with Swedish citizenship, who moved on loan from Dutch side Vitesse Arnhem.
Hearts completed the signing of 19-year-old Souttar just before the midnight deadline.
The Scotland Under-21 international was out of contract in the summer and United manager Mixu Paatelainen had previously expressed optimism over extending his stay but Hearts succeeded in prising him away from Tannadice after 73 first-team appearances. Souttar has signed a deal until summer 2019.
Neilson told Hearts News: "I'm really happy to get John here to Hearts. We see him as one of the brightest young prospects in Scotland, and one who we can develop further.
"John's a player who we've admired for a long time and I'm delighted to secure him.
"It shows the intent of Hearts to not only develop young players from our own academy, but recruit them too and continue their development.''
Hearts loaned Morgaro Gomis to Motherwell until the end of the campaign and Osman Sow is also understood to be on his way out of Tynecastle amid reports that a Chinese club had a £1million-plus bid accepted for a player who is out of contract in the summer.
Aberdeen signed Wales striker Simon Church on loan from MK Dons and loaned David Goodwillie to Ross County but failed in a move for Inverness midfielder Greg Tansey.
It is understood the Dons were angered by their Premiership rivals after believing they had met a release clause of about £200,000 in Tansey's contract. However, Caley Thistle would not allow the midfielder to speak to Aberdeen.
Motherwell failed to get anyone else in with general manager Alan Burrows writing on Twitter: "We're waiting on a couple of things to fall into place, but not going to happen just yet.''
But right-back Craig Reid departed and more signings could be imminent at Fir Park with an extended deal for James McFadden still a possibility.
Manager Mark McGhee said: "He was supposed to be going to America but that's fallen through so if he's going to stay around here, and if there's nobody else that steals him away from us, then he will be welcome to stay around here a bit longer.''
Partick were the first Ladbrokes Premiership outfit to conclude deadline-day business after signing former QPR trainee Antonio German. The 24-year-old forward has signed a deal until the end of the season after leaving Indian Super League outfit Kerala Blasters.
Meanwhile, Kilmarnock signed midfielder Gary Dicker from Carlisle and MK Dons right-back Lee Hodson on loan, two days after Gary Locke quit as the Rugby Park manager.
Inverness signed two midfielders but failed to bring in a striker. Ryan Williams joins from Brentford while Liam Hughes has completed a move from Cambridge following a successful trial.
The SNP claims a "Hard Brexit" will cost 80,000 jobs in Scotland.
