World Cup 2018: 3 things Switzerland did right against Serbia

#3 Getting the substitutions right

Petkovic hit the bull's eye with his timely and precise substitutions against Serbia

The Swiss head coach was well-aware of everything that went on in the game and thus, made the right substitutions through its length. He replaced Haris Seferovic with Mario Gavranovic at halftime and the decision proved to be crucial to Switzerland's victory on the day.

The striker was not just an upgrade on Seferovic's indifferent form on the day but was instrumental in creating and sustaining his team's attacking intensity in the second half. He assisted the second goal and was a vital cog to the turnaround in the game.

Breel Embolo, who was brought on for Blerim Dzemaili in the 73rd minute, also helped in adding dynamism and freshness to the Swiss front line, thereby creating a cauldron of consistent pressure around the Serbian defence.
