Pictures: Zinedine Zidane patiently waiting for Luka Modric as he perform his pre-match ritual

The Frenchman understands how important the pre-match rituals are to his players.

Luka Modric replaced Toni Kroos in the first half against Real Betis on Saturday with the German limping off with a potential injury.

Zinedine Zidane patiently waited for the Croat to finish his pre-match ritual of kissing his shin pads before giving out instructions to the 35-year-old.

Modric's shin guards have a picture of his wife and children on them and the midfielder always kisses them before coming on the pitch - without exemption.
