Ivica Olic looks to be on his way back to Hamburg, with Andre Schurrle increasingly likely to join Wolfsburg.
Midfielder John Rankin feels Dundee United could be on the verge of glory after agreeing a two-year contract extension.
The 30-year-old committed his future to the club until May 2016, two days after manager Jackie McNamara extended his stay until 2017.
The former Hibernian player, who has made 117 appearances for United, said: "The last three seasons have been the most enjoyable period of my career and I see the potential here right now and I want to be a part of that.
"The supporters are so encouraging and whilst that is important for the youngsters at the club it is also nice for us more experienced players.
"There is a positive vibe around Tannadice and we can achieve things in the near future here. We have shown progress over my time here and I think we are now ready to go to the next level."
McNamara declared the signing a major boost.
"John wanted to stay here and continue to enjoy his football and we are delighted with the job he is doing," the United boss said.
"We want our young players to learn good habits and both on and off the park John leads by example.
"He is a fans' favourite and securing his extension shows the fans we are intent on keeping our players and taking the club forward. The fans will be thrilled with this news and I am delighted that he will be part of my squad for a further two seasons."
