I don't totally agree with this statement, but I don't fault him, or any full-back tbh, if they get rinsed by Salah, or Saka, for example. They're two of the three best right wingers on the planet. And left-back isn't even Dalot's natural position.
The Liverpool match is a decent example. Yes he was playing against a top player who had a very good game getting 2 assists and a goal, yet there were several times Dalot came out on top in their duel. Despite Salah's end results being great, it wasnt all one way. Dalot made 3 tackles, 2 interceptions, 1 clearance, 1 blocked shot, 1 foul
I look back to last season when rival teams played Liverpool and Salah started.
Heres a 1 - 1 Arsenal and Liverpool.
Zinchenko makes 3 tackles, 0 interceptions, 2 clearances, 0 blocked shots, 1 foul
Dalot had more to do. And thats generally the case with our fullbacks. They have more one vs one defending to do than our rival teams because of how we play and how little of a threat we are coming forward, and the lack of support our fullbacks get with players doubling up compared to our rivals.
But if you have to face a top player having 10 chances to run at you and make something happen, vs 6 chances to run at the left back in another match, people will overlook the amount of good work you do if that player is making and scoring goals those times they get past you. Its a bit unfair because obviously the more a top player gets the ball in an area to hurt you the more likely it is to happen.
And you probably arent going to see many matches where the fullback Salah is against makes 4 tackles, 3 interceptions, 2 clearances, 2 blocked shots, doesnt give away any fouls and Salah doesnt get an assist or goal. Its not never. But its unlikely a player is going to do that unless Liverpool are playing a team who are sitting back and defending in shape all game and that player constantly has players around him helping him with double ups.
First assist for Salah, Casemiro plays a terrible pass and Dalot has no chance of getting back. Liverpool used the overload on the right and Salah was able to pick out a good cross with his right
2nd assist Dalot is showing Salah down the line and Lisandro should be tight enough on Diaz to intercept the pass or block the shot but he's given him too much room
For Salah's goal Mainoo and the Liverpool player go shoulder to shoulder and the Liverpool player emerges with the ball and Salah is already 10 yards behind Dalot. Never really an oppertunity to catch him before he turns it in. Given Dalot wasnt on the side of the pitch where play was happening perhaps he could have been 10 yards deeper when Mainoo had the ball. But thats it. Out of his man getting 2 assists and a goal all Dalot could have done differently is maybe have been 10 yards deeper one time. And people will say Salah destroyed him
