( CNN) There are few lonelier places than being the team's goalkeeper, especially when you're culpable for a mistake.

The 29 -year-old is an achieved cook and a fine photographer and composes his own songs in his spare time.

Rarely without his guitar, which has traveled with him to Russia, Sommer is as relaxed as you could expect with the pressure of the World Cup on his shoulders.

“I require some different activities away from football to help me switch off, ” Sommer told CNN Sport of his hobbies.

“Getting some distance from football is hard. There's so much pressure and when you go home you need to have something you are able to lose yourself in.”
