Arsenal fans react on Twitter to Alexis Sanchez's Chile performance

Alexis Sanchez Chile

Arsenal's Alexis Sanchez can't stop scoring.

Alexis Sanchez is well and truly back on form. After a slow start to the season, the attacker now has seven goals in four games for club and country.

The latest saw his him net for international side Chile during a 2-0 win over Brazil is their opening World Cup qualifier.

He followed up a goal from Eduardo Vargas to net an excellent team effort to seal the win in the 89th minute.

Sanchez had entered the game with fitness doubts over whether he would even play, substituted late on with an apparent injury in the win over Manchester United.

The forward had netted twice in that crucial win, and Arsenal fans would have been quite happy to see him sit out the international break, with an eye on the Champions League clashes with Bayern Munich later this month.

Sanchez is not the type of player to do so, fully committed to his country, where he is regarded as a national hero after helping them to their first ever Copa America win on home soil in the summer.

He has one more game to play next week before returning to Arsenal, which the club will be keen to see him come through unscathed. Fellow Premier League striker, Manchester City's Sergio Aguero last night picked up a hamstring injury playing for Argentina, the BBC reported.

Arsenal fans were impressed with their superstar's relentless form, here is a look at how they reacted on twitter...
