Davie Weir believes the lack of a scouting network at Rangers is a problem that needs to be solved.
Hull City have confirmed they have rejected a third bid from Norwich City for winger Robbie Brady.
Having only narrowly avoided relegation out of the Bundesliga in 2013/14, and having stumbled out of the blocks this term, there are more pressing issues to address at the Imtech Arena.
That means those hoping to see their futures resolved as a matter of urgency will have to be patient.
Hamburg executive Dietmar Beiersdorfer told Hamburger Morgenpost: “I can confirm that we have put everything on hold.
“We are not going to prolong any contracts at this point in time.
“First, we are eager to see what the players are capable of achieving through improved performances.”
Netherlands international Van der Vaart is the most high-profile figure to have entered the final 12 months of his current deal.
He was linked with a move away from Hamburg over the summer and may end up leaving as a free agent in 2015 if no fresh terms are tabled.
Germany internationals Marcell Jansen and Heiko Westermann are also being forced to wait on future talks, along with former Chelsea defender Slobodan Rajkovic, Gojko Kacar, Ivo Ilicevic and Jaroslav Drobny.
