Italy striker Antonio Cassano has left troubled Serie A club Parma after rescinding his contract.
Huddersfield striker Martin Paterson has joined Orlando City on loan until the end of the season.
Gordon Strachan has said it would be "an honour" to be asked to become Scotland manager.
The former Celtic boss, 55, is strong favourite to take over from Craig Levein. who was sacked by the Scottish Football Association on Monday following a poor start to the 2014 World Cup qualifying campaign in which Scotland have taken only two points from four games.
Former Celtic boss Strachan was asked about the Scotland job while working as a pundit on ITV's Champions League programme on Tuesday night.
He said: "It's quite simple really, it would be an honour to be asked to be the manager of your own national side, it's terrific.
"I could sit here and say 'yes, it would be great' or 'no, it's not for me' but it would also be arrogant of me to answer that if nobody has asked you and presume that someone will ask.
"Until you've been asked a question about a job, any job, then you really don't know how you'd go about it that's for sure. I wouldn't have the arrogance to think that someone is going to knock on my door."
Strachan spent four largely successful years at Parkhead from 2005 but has been out of management since leaving Middlesbrough in October, 2010.
