The 17-year-old South American starlet is currently plying his trade for Universidad de Chile - the same club that Eduardo Vargas was at before completing his move to Napoli.
The central defender only made his competitive debut in November, and has made a further three first-team appearances for Universidad de Chile this season.
But despite his tender age and limited senior action, Villas-Boas looks to have seen enough to try and secure his long-term future.
However, Chelsea's hopes of signing Lichnovsky have been dealt a blow, after it was confirmed that Serie A giants Inter Milan are also monitoring the situation.
"After Chelsea's interest, Inter Milan are now seriously interested in Lichnovsky," explained Robles. "I'm in continuous contact with the Italian club and they have asked me what price he would be available for.
"When Inter bid for Edu Vargas when he was at Unviersidad de Chilie [now at Napoli], they also expressed their desire to sign Igor."
