England midfielder Eric Dier has claimed that he "put a marker down" with his crunching challenge on Spain defender Sergio Ramos on Monday night.
The Tottenham Hotspur man was shown a yellow card for the 11th-minute tackle on the Roja captain inside the hosts' penalty area.
However, the incident seemed to set the tone, with England taking control of the first half as two goals from Raheem Sterling and a Marcus Rashford strike had Gareth Southgate's side 3-0 up at the interval.
Spain rallied after the break, with substitute Paco Alcacer pulling a goal back before Ramos grabbed a second with the last touch of the Nations League contest as the visitors secured a famous 3-2 success.
"I think it's really important that we respect our opponents and Ramos is one of the best of all time, really," Dier told Sky Sports.
"It's important to respect them, but at the same time, once we start the game, it's every man for himself and we have to put our foot down, put a marker down and be aggressive - still with respect, but we have to be aggressive, be on the front foot and show that nothing is going to intimidate us.
"That's just as important as playing good football and all the other aspects. I think Ramos is a great example of that. He does everything so well, but at the same time he puts his foot down and he's not going to be bullied. We have to be the same way."
