I don't think I misspoke at all, I really don't think he was near MOTM, he had a good game but there were other players that influenced the game more heavily and didn't really make mistakes, De Ligt being way ahead for example, I'd say he was pretty much flawless.
Amad had a good game, but given how good a couple of others were, his good game doesn't have him in the MOTM conversation.
The fact that I haven't named my top three players says the following - I was replying on my phone in the car and had to keep my replies short to avoid getting sick. But as it's important to you, I'd go with De Ligt, Martinez, Onana, with Amad in the honourable mentions pile along with Mazraoui.
Fair enough but I would still disagree and that's fine. No need for us to both agree but just for some context in case you may have missed it:
Martinez - when Dalot was getting no help down his left side and getting beaten, he uncharacteristically stayed in his box and didn't push out to help Dalot to cover that wing. Wasn't bad but wasn't his usual committed defending and that hesistancy caused an issue as we were pushed back; he left Dalot out to dry for a while before the goal. After the goal was calm with his passing and did well in that left channel in the second half but the game was already won as Southampton were neutered.
Onana - routine-ish far post save that he pushed back into the middle of the box (i.e not good) and then obviously came up with a fantastic penalty save, which sort of won us the game as it turned the momentum. Other than that, a few decent collected aerials and balls along the ground. After the goals, barely had anything to do.
de Ligt - sold himself for a very obvious dummy in the first half but was decent and then changed the tide massively with his goal. Was good with not much to do but had a few bad passes choices iirc. Almost recreated his mid-week Netherlands pass straight to another attacker in the second half.
Amad - before the goal, was pretty much the only outfield player who was retaining possession, whilst being an outlet off it and created several good chances with his dribbling and composure*. Also assisted for Rashford's goal with a very simple pass. Second half, made a load of tackles, attacked the channel, held the ball and again created a few chances.
*Zirkzee was good on the ball but wasn't a direct threat like Amad was.
Mazraoui - I don't remember any specifics but I did think he had a very good game on the ball and can't remember any defensive issues. I don't think Southampton attacked much down that side and he also had Amad doing a good job in front of him.
So in summary, as I had said before, to choose Onana and de Ligt as first choice MOTM, fair enough, wouldn't necessarily disagree. To put Martinez is a big stretch (and I'm a big fan of his) because most of his good work was after the goals when the game/tide was won. Mazraoui was good but Amad's influence was consistent before the goal (where Southampton dominated us in possession) and after.
