He will be the first Chilean to play for the Catalan giants and gave clear indications that he wanted to join them in preference to other clubs . `` He has been strongly committed to playing for Barca , '' the statement said . Sanchez will have medical before being officially presented at the Nou Camp Monday . Sanchez , who was voted best player in Serie A last season with 12 goals in 31 games , is Barcelona 's first major signing of the close season transfer window . In another major signing Thursday , Portuguese giants Benfica completed the signing of Spain 's World Cup winning defender Joan Capdevila from Villarreal . The 33-year-old left-back has been signed as a replacement for Portugal international Fabio Coentrao , who departed Lisbon for Real Madrid earlier this month .

Elsewhere , Dutch coach Ronald Koeman returned to football Thursday after agreeing to take the reigns at Dutch first division club Feyenoord . The 48-year-old has been out of the sport since leaving AZ Alkmaar in December 2009 and signed a one-year deal with the Rotterdam side . As a player , Koeman won the 1988 European Championships with Netherlands and the European Cup with both Barcelona and PSV . He also spent two years with Feyenoord between 1995-97 . Former Feyenoord coach Mario Been left the club after a disappointing season yielded a 10th place finish in the league and saw the one-time European champions humiliated 10-0 by PSV Eindhoven last October .
