Liverpool forward Diogo Jota has missed training with Portugal after missing the 3-0 friendly win over Qatar.

And Portugal boss Fernando Santos has confirmed Jota is in danger of missing Tuesday's World Cup qualifier against Luxembourg.

"He trained a while ago, increased the intensity today with (physio) Joao Brito, but he didn't train with us," said Santos.

"The probability [that Jota will play] will be little. I'll talk to him and see how he feels.

"If we see that he is in any condition to be on the bench and then he can come in, that's fine. If we don't, we won't take the risk with a player who hasn't been able to train with us for a long time.

"I'll make the decision shortly, and if he can't play, he'll head back to Liverpool."
