KEY BATTLES

ALEXIS SANCHEZ V JOSHUA KIMMICH

Chilean striker Sanchez has experience but has had a relatively quiet Confederations Cup. The 28-year-old will be the driving force behind his team's attack but will have to deliver better when it comes to finding the net.

He will come up against defender Kimmich, who has been playing with a maturity that belies his age. The 22-year-old is the only German to start the last 18 straight games for the national team.

However, Germany's defence has shown vulnerability, with Kimmich himself showing slight weakness in the air. Sanchez will try to capitalise on that, especially since he wants to impress big clubs after hinting that he is set to leave Arsenal in the summer.

GARY MEDEL V TIMO WERNER

Chile have to thank their solid backline for ensuring their progress in the tournament. They have conceded just two goals and this is mainly due to the stellar play from their centre-back Medel who has marshalled the defence well.

The 29-year-old Inter Milan player will have to use his vast experience to keep young Werner in check as the German striker has shown brilliant form in the tournament. The 21-year-old has three goals from his last two matches and is showing that he is a high-quality player who can be devastating.

ARTURO VIDAL V JULIAN DRAXLER

Chilean midfielder Vidal has been one of the outstanding players of this tournament. His no-holds-barred style was instrumental in subduing Portugal star Cristiano Ronaldo in the semi-final.

The 30-year-old, though, will come up against a canny opponent in German captain Draxler, who at 23 is the most capped German in Russia with only 34 appearances. Attacking midfielder Draxler has technical ability and pace on the ball and Vidal will have to nullify that to ensure that Germany's frontline does not thrive in St Petersburg today.
