Alex Oxlade-Chamberlain was less than impressed at being hooked during Liverpool's 1-0 win over Nottingham Forest on Sunday.
The England international has struggled for game time this campaign and was keen to make an impression in the FA Cup, but a poor display saw him subbed on the hour mark with the scores still level. ITV cameras focused on Oxlade-Chamberlain as he made his way off the pitch, and he appeared far from happy with Jurgen Klopp's decision.
Oxlade-Chamberlain appeared to mutter something under his breath, although what he said has been debated by Liverpool fans, with some suggesting he was bemoaning his lack of game time and others claiming he referenced the formation being changed.
