Dundee United admit they face competition for the signature of David Robertson as they continue talks with the midfielder.
United manager Peter Houston said: "The chairman met David's agent and talks are ongoing.
"It won't be something that is decided in the next few days because he has other options.
"The talks were positive, we know what he's looking for and will be making him an offer."
The 24-year-old former Scotland Under-21 international came through the youth ranks at Tannadice before becoming a first-team regular.
Houston expects Robertson to make up his mind about whether to extend his stay on Tayside in the next few weeks.
"He has other people interested in him, so it will be up to David whether he wants to remain here or move on," added the United boss.
