James Milner believes the experience Manchester City and Chelsea players have gained this season could be key for England this summer.
There are four City players in England's 23-man squad for the European Championship in Poland and Ukraine and they arrive having clinched the club's first league title in 44 years.
That came about in dramatic circumstances on an extraordinary final day of the Premier League season, but Chelsea matched it with their astonishing efforts to win the UEFA Champions League.
Frank Lampard, Gary Cahill and Ashley Cole starred as Chelsea overcame Bayern Munich on Saturday, while the suspended John Terry also joined in the euphoric celebrations.
And Milner believes all eight men will be boosted by their achievements in recent weeks.
The 26-year-old said: "Our players are going into the tournament on a high and high on confidence and that's what you want.
"You want to get into those habits of winning trophies and that winning mentality and if players have had the taste and had a good season it's only a good thing for us as a team.
"Both occasions were pretty special - lots of tension and ups and downs during the games and that's the beauty of football.
"It's a couple of great achievements and the confidence that you get from winning trophies can only be a good thing."
Chelsea's players have not yet linked up with the squad as they are enjoying an extended rest following their European exertions.
That has played its part in England manager Roy Hodgson's decision to cancel a training camp in Spain and have a brief get-together in Manchester instead.
It's a decision Milner backs - especially given the unexpected heat-wave the country is enjoying.
Asked if he agreed with the decision to cancel the Spain trip, Milner said: "I think you can go about it both ways really.
"The lads are ready to go and I think we're getting the best of the weather here - that's why we've come to Manchester for the sun and that prepares us for getting out there as well.
"I think the lads are happy and obviously the Chelsea boys are getting some rest too which is much needed and hopefully we'll be ready and raring to go for the tournament."
With Hodgson only appointed earlier this month, the training sessions this week have been Milner's first experience of working with the new England boss.
And the City midfielder feels Hodgson has succeeded in getting his messages across at an early stage.
"We've had a good couple of sessions; quite tough," said Milner.
"We've had a few days off and he really just wants to get across how he wants us to set up and play.
"His thoughts when we've got the ball and when we haven't got the ball, that's the biggest thing.
"Although we've only had a couple of sessions and we haven't got some members of the squad here as well, I think we've had a good couple of sessions.
"The lads are getting pretty clear on how we're going to set up and how we're going to play."
Milner was a fixture in the England squad under Fabio Capello but there was an air of uncertainty around the inclusion of most of the squad given that this was Hodgson's first selection.
And the former Aston Villa man admits he could not be certain of his place.
"You hope that you're going to be in it but you're never sure until you get the call or text and it was pleasing to get that," added Milner.
"Hopefully I can contribute and have a good European Championship."
