Tel sparked outrage among Tottenham fans when he appeared on social media wearing a Fulham William shirt

Recently, 19-year-old forward Mathys Tel, currently on loan from Bayern Munich, posted a photo on social media wearing the jersey of Fulham winger Willian, which sparked outrage among Tottenham fans.
The background of this story dates back to the summer of 2013 when Willian was set to join Tottenham and had already passed the club's medical exams, but at the last moment, he changed his mind and opted for Chelsea instead. Willian later publicly stated that this was the best decision of his career, which fueled the animosity from Tottenham fans. Additionally, his subsequent transfer to Arsenal only added fuel to the fire.

Now, Tel has deleted the social media post and apologized to the angry Tottenham fans in the comments section, saying, "Sorry, I didn't know (the background story)."
