Nathan Redmond and James Ward-Prowse will be "fired up" to prove themselves again next season after being left out of Gareth Southgate’s Nations League squad, according to former England defender Viv Anderson.

Saints pair Redmond and Ward-Prowse were not included in the final 23-man squad for Portugal along with Tottenham duo Kieran Trippier and Harry Winks in what Southgate admitted were difficult choices to make.

Rather than be discouraged, though, Anderson believes the healthy competition for places will drive everyone on for continued success as England look to maintain momentum from the World Cup all the way to Euro 2020.

The 62-year-old, capped 30 times and in two World Cup squads, believes call-ups for the likes of Redmond and Ward-Prowse shows Southgate will reward consistent domestic form - no matter at which club.

"Guys like (Bournemouth striker) Callum Wilson, the lads at Southampton - James Ward-Prowse and Nathan Redmond, all at so-called unfashionable clubs, it (being called up) is a great example to any English players in the Premier League," said Anderson.

"They are young, hungry and enthusiastic players who want to do well.

"If Gareth can look at it, put one or two in to freshen it up, then why not?

"It gives them an opportunity to show what they can do at the top level."

He added: "The manager has found a formula which suits him, and I think he will have explained to guys like Kieran and anyone else he had to leave out the reasons behind it," said Anderson.

"Most people will understand it and they will get themselves fired up by it, to make sure they get themselves back into the next squad and then again in the one after that.

"It is the fight for places which everybody wants - we don't want the same people knowing they can just get in even if they have had a mediocre season or whatever. We want to give challenges to all positions."
