Reports in Croatia suggest Chelsea have entered the race for highly-rated defender Dejan Lovren.
The 20-year-old, who is currently on the books of Dinamo Zagreb, is regarded as one of the hottest properties in his homeland.
French giants Lyon have already made a move for his services, but have seen an official approach knocked back.
Dinamo insist they have no plans to part with Lovren, but vice-president Zdravko Mamic has admitted that stance could change were they to receive a suitable bid.
"Lyon made an offer which we didn't accept," he said.
"That is the end of the story. Many will say I'm totally mad because I didn't accept an offer from France, but the point is we are in no hurry.
"Our financial situation is quite good and we don't need to accept just every offer that comes along.
"We want to build a strong team for the future, we want to be better and better. And we are not offering anybody to nobody.
"Not Lovren, not (Mario) Mandzukic who is constantly linked with Werder Bremen. We will only sell in case of an offer which would be impossible to refuse."
Speculation suggests that Dinamo could be tempted into a sale if they receive an offer of €10million (£9m).
