Adam Lallana insists he was not at all surprised to see Southampton team-mate Luke Shaw named in the England squad for Wednesday's friendly against Denmark.

The 18-year-old Shaw is in line to be handed his first cap as Roy Hodgson looks to finalise plans for who will make his 23-man World Cup squad.

The Saints left-back has enjoyed a good season to date and Lallana has backed Shaw to take to international football with similar ease.

"I'm not surprised at all," he said when asked about Shaw's involvement.

"He has been an outstanding for us all season. He looks like a seasoned pro and it was no surprise to see he was included in the squad.

"There are two outstanding players ahead of him (Ashley Cole and Leighton Baines) but he will keep his feet on the ground.

"He knows he is going to learn off them and if he watches them closely in training he knows it is going to do him good."

Lallana and Shaw are joined in the 30-man squad by Saints team-mates Rickie Lambert and Jay Rodriguez as the south coast club have four players in the senior England squad for the first time.

Lambert was the first of the quartet to break into Hodgson's squad and Lallana revealed the striker's inclusion gave Southampton's other English talent renewed hope of making the grade.

"Seeing Rickie being involved gave everyone an extra 10 per cent of belief," he said.

"We have had a good season at Southampton, been performing well on a consistent basis and we have all been helping each other.

"It is brilliant, it proves how far the club has come and to have four lads representing the country this week is fantastic."

Arsenal's Alex Oxlade-Chamberlain, who returns to the Three Lions squad for the first time since August following a long-term knee injury, made his England bow at the age of 18 - with Shaw set to emulate that feat on Wednesday.

Another product of Southampton's academy, Oxlade-Chamberlain said of Shaw: "It is really good to see him here.

"I think he has been absolutely outstanding. The maturity he has been playing with and the consistency level has been unbelievable.

"He shot up and has matured and grown physically, he has taken that into the first team at Southampton and it has been a rapid rise for him but he has handled it really well."

Oxlade-Chamberlain travelled with England to Ukraine and Poland for Euro 2012 as a young player and admits the experience will help him in the future.

"For me, going to the Euros was a massive experience and it almost came as a surprise to see my name selected for that," he added.

"It gave me the pedestal to push on with my Arsenal and England career. Seeing how Steven Gerrard and Wayne Rooney handled themselves at a major tournament was a great experience for me."
