Alexis Sanchez is set to join Barcelona from Udinese for a fee of £23m, which could rise as high as £33m.
The Chilean winger, who will undergo a medical on Monday, has signed a five-year deal with the La Liga and Champions League holders.
Sanchez, 22, was voted Serie A's best player last season having scored 12 times in 31 games.
Sanchez, who has 40 caps for Chile, signed for Udinese in 2006 from Chilean side Cobreloa.
