I’m not sure I agree with the Kalimuendo example. He never looked great when he came on. Igor Jesus looks a much better goal scorer in Europe than he does in the premiership. He’s the same player but has way more time to take an extra touch in European games. When he tries that in the premiershipleague, he gets snuffed out. So you can argue that it’s about adaptation to both the team and the league.
Certain players look better under certain managers. Nuno refused to play (or speak to) Omari and he didn’t get much gametime under Ange but has looked good, particularly off the bench under Dyche. Similarly, even you will admit Sangare looks good in a Dyche side (with the notable exception of Friday evening). Luiz looked awful under Dyche but great under Ange (and Emery).
