Real Madrid Eight assists from a corner in 2016/17

Zidane has to rotate in April

One of Real Madrid's most lethal weapons this season has been Toni Kroos' sniper-like corner kicks.

So accurate have they been that one of the corners of the Estadio Santiago Bernabeu should be christened Kroos Square.

It's his favourite part of the ground and from where he is most lethal.

Without the German, we would not have the magic story of Sergio Ramos and his headers.

Together they form a perfect couple, that just this week has been decisive again.

Three of Madrid's five goals in the last two matches against Napoli and Real Betis came from the German's precision from the corner, and the strength of the central defender to finish them off.

Maximum accuracy

With a team of specialists in the aerial game - Ramos, Varane, Pepe, Cristiano, Bale, Morata and Benzema - Kroos' precision is a key trick in attack

Ramos' goal in the 2-1 win over Betis meant the midfielder has supplied eight assists from corners so far this season.

Two for Cristiano Ronaldo, two more against Osasuna for Ramos and Pepe.

Another brace against Malaga and finally two for Ramos against Napoli.

Zizou's Lab

The German is the head of Zidane's laboratory.

Well covered also by Modric and James Rodriguez, other specialists in the execution of the strategic plays, the French coach has unleashed Kroos' full repertoire.

So what if he is doing even more than he would like, because it is this strategy that is saving Madrid in many games.

Kroos does not score many goals per season, in fact he has just five for Real Madrid in official matches, but has registered 42 assists.

This season he's already just one away from equaling his best record in a season; the 15 he managed in his debut campaign in the Spanish capital.

Being in March, he has the opportunity to pulverize the record.

For the moment, what he has achieved is to make his corners decisive.
