Inter will launch a final assault for Udinese's highly-rated fantasista Alexis Sanchez in the next seven days, according to La Gazzetta dello Sport.
The Chile international reportedly has his heart set on a move to San Siro in January, even though Udinese would like to hold on to him until June.
Inter's chief technical director Marco Branca has held a number of talks with his counterparts at Udinese about the prospect of signing Sanchez.
La Gazzetta dello Sport understands Inter President Massimo Moratti has given Branca the green light to make an offer for the 22-year-old who was impressive against Milan on Sunday afternoon, scoring a goal in a 4-4 draw.
Inter had initially made a bid worth €18m for Sanchez plus Jonathan Biabiany in exchange, only to see it turned down.
Udinese are thought to be holding out for €25m in cash, but Branca will improve his first offer by €2m and put Obi's contract on the table instead of Biabiany's.
The thinking behind this move is that Udinese would have a replacement for Gokhan Inler should the Switzerland international leave for Napoli.
