Sanchez was introduced as the newest Gunner on Thursday, agreeing to terms on a four-year, £30 million contract, The Telegraph reports. Sanchez made a total of 88 appearances for Barcelona, his previous club, scoring 39 goals during three seasons in Spain.

Sanchez is very much in his prime at age 25, and he's the most gifted offensive player at the Emirates since Robin van Persie departed two years ago. Expectations will be high for Sanchez in his Premier League debut, and they should be.

Barcelona and Arsenal have agreed to a transfer fee for Sanchez in principle, but Barcelona is waiting to see if Juventus will match the offer, reports the Daily Mail.

Sanchez indicated earlier that he did not want to join Liverpool, and the team went ahead and agreed to a potential transfer with Arsenal. The London club may land the striker if Juventus is unwilling to match the offer.

Arsenal is working on acquiring Sanchez, according to BBC Sport.

The Sanchez-to-Arsenal move could also depend on whether or not Barcelona lands Liverpool striker Luis Suarez. Barca are reportedly seeking a fee of at least £25 million for Sanchez. The Chilean striker had 19 goals and 10 assists in 34 La Liga games last season.

Sanchez scored in the 12th minute and then set up Jorge Valdivia in the 14th during Chile's 3-1 win over Australia in their opening match of the World Cup on Friday.

Sanchez is the spark in the Chile attack and he showed early on how effective he can be. The Barcelona midfielder, who had 19 goals and 10 assists in 34 La Liga appearances last season, will face off against many of his teammates next Wednesday when Chile face Spain in a huge match after the Spaniards lost 1-5 to Netherlands on Friday.

Sanchez scored in the 67th minute of Barcelona's 2-2 draw with Getafe.

Sanchez has now recorded an impressive 18 goals and 10 assists in 32 appearances this season, a significant jump from the eight and nine he had last year, respectively, although those came in just 18 games.

Sanchez scored in the seventh, 63rd and 69th minutes of Barcelona's 4-0 win over Elche on Sunday.

Sanchez has now reached double-digit goals in league play for the third time in his career. His 11 goals in the Spanish league this year now trail only Diego Costa (19), Cristiano Ronaldo (18), and Antoine Griezmann (12).

Sanchez scored in the 71st minute of Barcelona's 4-0 win over Granda on Saturday.

Sanchez now has eight goals and two assists in 10 Liga appearances this season, the former of which is beaten by only Cristiano Ronaldo (17) and Diego Costa (14) so far.
