Chelsea full-back Cesar Azpilicueta has been handed a new five-year deal by the Premier League leaders.
Scottish FA confirms it will apply to FIFA for an exception to help push through John Guidetti's loan move to Celtic.
Dundee United have insisted they have received no offers for any player amid reports of interest in some of their young stars.
Reports on Friday claimed Ipswich were monitoring defender Gavin Gunning while Swansea were said to be lining up a bid for winger Gary Mackay-Steven.
But a statement from the club read: "Dundee United are disappointed to read what we regard as unsubstantiated rumours in today's media relating to our players.
"We have received no formal offers for any of our players and indeed would not welcome any such offers.
"We are realistic of the current financial climate within football and if substantial offers for any of our players which exceed the valuations we place on our players were submitted, we would consider such bids.
"The manager is currently engaged in attempting to enhance the squad for next season after another highly successful campaign and each of our contracted players are seen as integral parts of our future squad.
"We remain committed to providing our loyal supporters with the best possible team on the park."
One player set to leave is midfielder Danny Swanson, who has made only 14 starts in two seasons amid a series of injuries.
Both player and manager Peter Houston have agreed it might be best for him to move on.
Swanson may be allowed a farewell appearance against Motherwell at Fir Park in the final Clydesdale Bank Premier League game of the season.
Houston said: "I'll have a think about possible changes before coming to any decisions.
"However, irrespective of the teams I chose we'll be going there with only one thing on our minds which is to win the match.
"Motherwell are a very good team and deserve all the credit going for getting into the Champions League qualifying stages.
"It's taken a lot of hard work so we respect what they've done.
"But we still want to go out with a victory under our belt and I know I've got a good bunch of professionals in that sense.
"They've worked ever so hard throughout the whole of the campaign and I know they'll do the same on Sunday."
Houston, whose side have clinched a Europa League spot, added: "It would be great to give the supporters one last thing to shout about at Motherwell.
"They really deserve it because they've been absolutely magnificent this season.
"The United fans have backed us both home and away this season which the players really appreciate.
"I'm not sure how many will be going on Sunday as it obviously costs quite a lot of money to get down from Dundee to Motherwell.
"But hopefully there will be a good turnout and we can finish the season on a high.
"I hope the fans appreciate what the team have achieved this season and I'm sure they do."
