Joao Felix was once touted as football's biggest prospect. After bursting onto the scene in Portugal, it wasn't long before comparisons with his fellow countryman Cristiano Ronaldo were made.
Atletico Madrid certainly believed the hype, forking out £114m to sign Felix from Benfica in 2019 - the same year he won the Golden Boy award - making him the most expensive teenager ever in the process.
But, a little under six years later, Felix's career only appears to be going one way after hitting a new low on Sunday.
The 25-year-old forward - who has cost clubs £171m in transfer fees - was involved in a heated exchange with England's Kyle Walker as AC Milan emerged from the tunnel for the second half of their Serie A clash with Napoli.
