I see Charles as best played in a three man midfield more advanced from central/defensive midfield duties, or in the Azaz attacking midfield role. With Saints he's been less impressive when asked to dig in and play a defensive midfield game. He has the pace and athleticism to thrive as a 10 and play higher up the pitch. The improvement in his game since he joined SW in late 2024 is clear though he's not yet the finished product. Also seems to thrive in a faster more open game, compared to some of the physical, congested Championship matches; the three FA Cup matches against Prem opponents this season showed as much.
Don't understand the claims that he's over-hyped - the best is yet to come for him. Whether it's with Southampton or a Premier League Club is the intriguing unknown.
