Inter are thought to be fighting Arsenal, Borussia Dortmund and Barcelona for 21-year-old Austrian defender Aleksandar Dragovic.
The international is currently plying his trade for Swiss side Basel, but is wanted by numerous top clubs across Europe.
He has a contract until June 2015 and according to Austrian media the price-tag has now risen to €10m.
Inter are looking for a new centre-back after Lucio confirmed he would be walking away this summer.
