According to The Mirror, the 22-year-old winger, who was left out of Joachim Low’s 23-man Germany World Cup squad, was distraught over his omission, but claims he will use it as motivation going into the new season.
Last season’s PFA Young Player of the Year stated: “Yes, of course it gives you motivation.
“It was a shock when I was told, of course it was. I was disappointed at the time and it was really hard for the first week. But now it’s just made me want to come back really strong.
“It was a surprise because I thought I’d played quite a good season. Like I said, I was disappointed and I’m still feeling it a bit, but it’s another season for me and I’m looking forward to it.”
The left winger, who scored ten goals and provided 15 assists in the Premier League last season, is currently on tour in the United States with his City team mates.
Germany suffered a shock exit out of this summer’s World Cup, after finishing bottom of their group that was topped by Sweden and Mexico, ending the tournament with just one win.
Sane, despite his displeasure over his exclusion from the squad, stated: “Yes, I watched it - it’s the World Cup! When I watched it, I had the feeling that I wanted to be there. But I’m 22 and I still have a lot of years to prepare.
“I was disappointed for the guys because some of them are my friends and I’ve played with them before. They are all good guys and that’s why I was disappointed for them. The World Cup games are special and losing them hurts more than other ones.”
