Brazil could only put the ball in the back of the net three times from a total of 43 shots in poor performances in their 1-all draw against Switzerland and last minute 2-nil win over Costa Rica. 

In both matches they controlled proceedings with more possession and successful passes but even with the attacking talent like Neymar Jr, Gabriel Jesus and Phillipe Coutinho, Brazil couldn't break the shackles off their feet and seriously punish team like they did in qualifying. 

Enter head coach Tite ahead of the must-win Serbia match to qualify for the knockout phase. Surprisingly he went with the exact same lineup that couldn't break Costa Rica down until the 93rd minute.

But something had been changed in their approach which could improve Brazil's chances of installing some fear in their opponents and finally unlocking their potential at the World Cup. 

Tite's changes centred around the positioning and movements of three players; Coutinho, Paulinho and Gabriel Jesus. 

Gabriel Jesus was executing his game plan like any other match against Switzerland and Costa Rica, playing on the shoulder of the last defender and trying to get in behind onto craft passes from Neymar and Coutinho. 

However, both sides sat very deep, soaked up pressure and pressed on the counter attack. Tite had no answer but to throw the kitchen sink at them which left them vulnerable but he tweaked the role of Gabriel Jesus a little to open up avenues for attack without completely opening themselves up. 

Tite instructed Jesus to drop deeper and look to receive the ball and play off to Neymar who would be making a run in the inside channel.

Reason being, Jesus would be dragging the opponent's central defenders out of position in this case Serbia's Milenkovic and Veljkovic and with Paulinho making instinctive marauding runs forward, if successful it would create a 2v2 attacking situation on the cusp of Serbia's defensive third.  

The 18th minute showed a glimpse of how Brazil intended to execute their game plan. Felipe Luis carried the ball forward and fizzed a pass into Jesus who dropped deep bringing the defender out of position allowing Paulinho to make the run inside, he laid it off for Coutinho who dinked a ball in that just had too much power. 

The plan reaped rewards just after half an hour as Brazil took the lead with their new game plan. Jesus targets Veljkovic, getting close to him and making sure he follows his run, Jesus int eh build up does not even touch the ball, but instead runs across Serbia's other centre-back Milenkovic till the two central defenders are virtually next to each other. 

Before you know it Paulinho has penetrated that space and gets on the end of a delightful chip in behind to put Brazil up 1-0.
