The Netherlands international has attracted the interest of a number of top teams with his outstanding performances in the 2011-12 campaign, with the Reds keeping tabs on him
The 21-year-old forward has been in fine form this season, netting 23 goals in 30 Eredivisie appearances, and his good performances have not gone unnoticed elsewhere.
"Liverpool are closely monitoring Luuk. But there are at least 15 more teams who are after him. Three big teams that have qualified for the Champions League preliminaries have told us that they are ready to open talks with Twente," Laros stated to Voetbal International.
"We will keep our eyes and ears open in the next few weeks. Luuk is feeling very well at Twente, but if the club fails to qualify for Europe, staying put is a less attractive option."
De Jong has a contract with the Eredivisie side until the summer of 2014, and an offer in the region of €15 million (£12.2m) could be needed to lure him away from Twente.
The forward has previously been linked with Newcastle United and Borussia Monchengladbach.
