The Frenchman had been working hard throughout the game to get the ball forward, creating plenty of chances, taking on Trent Alexander-Arnold in the process.
However, he was taken off for Mata as Man United failed to find the back of the net and claw back the 1-0 lead from James Milner’s penalty in the first-half.
Here’s what fans on social media had to say about his performance.
Martial gets no support from him. No overlaps. No runs to distract defenders. Almost an impossible job.

The Martial sub doesn't make sense especially for Mata, if Rashford okay

Why take off Martial?

When Martial was taken off, it felt like there was no pace moving forward for United and it was something Marcus Rashford would have solved with ease.
The Frenchman has been criticised in recent times for his performances, but he had a brilliant impact against Liverpool and looked like he could have scored at any moment, which is why his substitution came as such a surprise.
He’s been on the road to finding his best form again at United and hopes are we’ll see him in action against Stoke City next Saturday.
