Manchester United Champions League winner Rio Ferdinand says Jadon Sancho will be upset with his England snub.
Sancho was overlooked for the matches against Italy and Germany later this month - the final squad before Three Lions' boss Gareth Southgate names his World Cup party.
Ferdinand said: "Jadon Sancho will be one player who will probably look at that squad and think I've done what's expected of me as a winger in terms of output, numbers-wise this season and I'm doing better in terms of numbers than other players, and I'm still not getting a look in.
"He could probably feel disgruntled."
The 43-year-old also suggested that while he understands some players coming into the set-up without playing regularly, it is concerning when there are several players included.
He added: "You gain trust through performance. This England team have gone and done things that our generation never got near doing and that counts for something. I understand the odd player coming in when they haven't been playing at club level, but when you've got more than the one... I'd look at it as a player, I'd be concerned. I've been in squads where players have come in and haven't played for long periods and haven't hit the form as they're used too.
"I'm thinking, I hope you get more minutes by the time the World Cup comes because I don't want you coming in rusty, I want you ready to play and in motion with momentum, which is key."
