Jamie Carragher claimed Maurizio Sara "really hurt me" with his treatment Callum Hudson-Odoi.
Sky Sports pundit was furious that Chelsea boss criticized the debut of 18-year-old England after the first 20 minutes only to watch.
Before you even start the match in the premier & # 39; er League for Chelsea, Hudson-Odoi made his Three Lions bow for a 5-0 victory over the Czech Republic.
Sarri but admitted that he excluded the 2020 qualifiers Euro, because he wanted to see some of his other players.
He said: "I watched England for 20 minutes, he did not start very good thing, but done very well on the left as I know, that he prefers to play on the left …"
Hudson Odoi was dropped to the bench again in a clash with Cardiff and Carragher took a swipe at Sarri before the start of the match.
"My big problem"
Liverpool legend said: "I have no problem with him privately say that to the player, and possibly public is not the end of the world.
"My biggest problem is that said Sarri on the Hudson-Odoi – and it really hurt me, because I put myself in the position of this guy – he said:" I just watched 20 minutes and 20 minutes, I hour, he did not play what is good. "
"This is a guy who is making his international debut, why you do not see the full version of the game, number one?"
Chelsea wants to tie the Hudson-Odoi down with an incredible £ 100,000 a week deal, but the 18-year-old does not want to put pen to paper.
Bayern have expressed their interest, while the prime minister's & # 39; er League rivals Manchester United have also been linked.
And Carragher, 41, claimed that the negative comments Sarri could damage the chances of maintaining his club.
"Now, you could argue that he was watching some of his Chelsea team-mates, clicking on the different channels that you want.
"But you should not look at them, it is about 27/28/29. This is a young guy, he can handle the spotlight to play for England? This guy, I try to keep in my club.
"So do not just dismiss the international debut of the guy who might be the greatest thing that ever happened to him in football at a young age.
"I can imagine people above Sarri just shook their heads and thought:" Why are you talking such nonsense in the press conference?
"I would not be surprised if the people at the top of Chelsea were on the agent to try and calm the situation, because you can imagine how bad you feel.
"If he was not looking, and he does not think he played well, be smart and use your brain. Say you're watching it.
"But what he said about the player, of course it should be improved, it is still a child. But to dismiss someone on their international, I think it's a stupid thing to say. "
