30. Jack Grealish
It’s a sad reality that players don’t stay with their childhood teams anymore. Instead, these elite athletes chase the money but nobody can blame them. This doesn’t mean that they don’t leave their teammates high and dry. That’s exactly what Grealish did to Aston Villa (via The Athletic).

The English forward became a Villa icon after his exciting displays for the team. But he wanted more money and the chance of silverware. The writing was on the wall as soon as Manchester City made their interest known. He joined for a massive fee in 2022 and Villa struggled all season.
