It seems so obvious when you think about it, but selecting midfield clubmates to play together at international appeared to be a stroke of genius by Roy Hodgson at Wembley.
For too long England's team has been about picking 'the best' players, irrespective of their ability to gel, and throw them together in the hope it works.
In key areas like central midfield and central defence this is especially important, but rarely have the Three Lions had the opportunity to put this into action.
The most famous case in recent years was the numerous attempts from various England managers to get Frank Lampard and Steven Gerrard to play together.
Sven Goran Eriksson, Steve McClaren and Fabio Capello kept trying, at the expense of shoving Paul Scholes on the left, and leaving Michael Carrick out entirely.
Now England have an alternative, in Tottenham Hotspur's rising duo Dele Alli and Eric Dier.
Individually both are raw prospects, and if asked to select England's best two midfielders, while there are no candidates head and shoulders above the rest, it would be a push to suggest they would both feature.
Dier may not be everybody's choice, but his combination with Alli surely makes him a better option than selecting Alli and Fabian Delph and hoping it works, when Roy Hodgson has an option which already does.
Their individual strengths are combined by the fact they know each other's games, can play together, and are only likely to get better.
This gives them both an edge in terms of not only selection for Euro 2016, but actually succeeding when they get there.
