"To win like we did will only strengthen it and overall we have good ingredients in the squad and it is a good opportunity again to show it away from home".
It's little wonder some of Europe's elite might look to poach the Chile worldwide after Arsenal finished fifth in the Premier League last season. Why hasn't he just said I'm staying for one more season?
