He returned home after watching football for 11 years
Swiss club Basel fan Roof Bentel arrived in Milan, Italy in 2004 to support Inter Milan in the Champions League. He went to the toilet near the end of the match and when he returned to the stands he could not find his friends. He also has only 20 euros. I don't have a phone. So he slept in Milan for 11 years. During his time in Milan, he supported Inter Milan's arch-rivals AC Milan. In 2015, authorities only found out about him when he was admitted to hospital with a broken leg after a fall. He contacted Swiss authorities and deported him to Switzerland.
