Widely regarded as one of football’s most influential managers, Van Gaal boasts a resume that spans several of Europe’s elite teams. He made his mark at Ajax in the 1990s, famously leading the Dutch club to UEFA Champions League glory in 1995, a triumph that solidified his reputation as a tactical mastermind. He later took the reins at clubs including Barcelona, Bayern Munich, and Manchester United, where he won multiple domestic titles. His time at United included an FA Cup victory in 2016, which turned out to be his final game in charge of the English club.
