Shaun Maloney has left Championship strugglers Wigan to join Major League Soccer side Chicago Fire.
Fiorentina winger Juan Cuadrado has made it clear he wants to join Chelsea, Sky sources understand.
Stuart McCall is the latest candidate to rule himself out of the running to succeed Craig Levein as Scotland manager, admitting the job has come a decade too soon for him.
The Motherwell boss had been tipped as an outsider to take over the national team after Levein was sacked on Monday.
Another contender, Alex McLeish, also distanced himself on Tuesday from a return to the post he occupied in 2007.
As far as 40-times capped McCall is concerned, McLeish is just one of five managers he believes are better qualified than himself for the post right now.
He said: "If it was to come about in 10 years' time it would certainly be a job I would be honoured to do.
"It would be an absolute honour. Despite the accent, I'm as patriotic as any Scot.
"The biggest playing highlight I've ever had was making my debut. I managed to play 40 times and it's something that will always live with me.
"But there are five greater candidates out there than myself, with greater experience and knowledge.
"There are some terrific candidates. I think it's a job for an experienced manager."
Gordon Strachan has quickly emerged as the bookmakers' favourite and, as well as McLeish, McCall also rates Walter Smith, Owen Coyle and Joe Jordan.
He said: "If you look at the candidates there are two managers who have already managed the national team, Alex McLeish and the best manager I've ever worked for, Walter Smith.
"There are two other men, who are great football men, with a lot of respect for them, in Gordon Strachan and Owen Coyle
"Then, somebody who was my boyhood idol, Joe Jordan.
"There are some great candidates. I'm very flattered to be linked with it but there are more knowledgeable and experienced men out there who can do a good job.
"At the minute Gordon Strachan seems to be the favourite and I think that would be a terrific choice, as would all the ones I've mentioned, to be honest.
"We are quite fortunate that there is such a calibre of manager who, hopefully, want the job."
Levein was sacked by the Scottish Football Association following a poor start to the World Cup qualifying campaign, which leaves Scotland bottom of the group with just two points from four games.
McCall had some sympathy for Levein, adding: "I'm sad to see Craig lose his job. We actually made our debuts together against Argentina back in 1990.
"A couple of little things have just not gone his way.
"I think we all know for managers it is all about results but I'm disappointed to see Craig go."
Levein's successor is unlikely to be McLeish, who has distanced himself from a Scotland return, while backing Strachan for the job.
He said: "I left the national team to take up club football, I felt I was missing the day-to-day stuff.
"I'm still of that mind. I wouldn't like to be unfair to the Scotland fans in terms of coming back to the job. A lot of people would maybe think I was a hypocrite."
Speaking on talkSPORT, he added: "Gordon Strachan is a pretty good candidate to me.
"He's had success at club level with Celtic. Whether he wants to come away from the television role he's got - because he's very good on TV - would be a big decision for him to make."
Interim national team coach Billy Stark will name the squad for this month's friendly against Luxembourg at a media conference at Hampden at 1215 on Wednesday.
The SFA have confirmed that Under-21s boss Stark will be assisted by Donald Park for the match on November 14.
Ricky Sbragia will take charge of the Under-21 squad for their friendly against Portugal, also on November 14, and he will be assisted by Dean Gorre and Scott Booth.
Meanwhile, Scotland international Scott Brown refused to be drawn on Levein's departure, insisting his full focus is on Celtic's Champions League clash with Barcelona.
Asked if Levein should have been given more time, the Hoops skipper said: "Not for me to say. I am just here to concentrate on Celtic versus Barcelona tomorrow."
He added: "It's hard, to be fair. It is disappointing to see him go but we are not too sure what is going to happen."
