Following Manchester United's Premier League draw with Liverpool on Sunday, Ole Gunnar Solskjaer explained his decision to substitute Bruno Fernandes, who did not look at all happy with his manager's call at the time.
The Portuguese midfielder was brought off with a minute left of regular time, and did not appear pleased with Solskjaer's decision to remove him from the field of play.
Fernandes was seemingly unimpressed with his number being shown on the board, especially as Scott McTominay had gone down clutching his leg just moments earlier. The Scot, however, was fit enough to continue and the Portugal star was thus substituted for Mason Greenwood.

A few angry and frustrated gestures from the midfielder left many wondering about the incident, but Solskjaer later played it down, explaining that Fernandes has been run into the ground of late.
"It was a tactical decision, Bruno has been running his socks off every single game," he told Sky Sports.
"Towards the end, we thought Paul's physical presence might be a chance and Mason can score in a blink of a second. It was a bit of a throw of the dice."
Fernandes has been substituted in each of his past three league starts for United.
