Referee Ovidiu Hategan brandished four yellow cards in the opening 45 minutes, and Chelsea full-back Cesar Azpilicueta was fortunate to escape a potentially serious injury after being caught by a high lunge from Leicester striker Jamie Vardy.
Azpilicueta was left reeling in pain as Vardy caught the the defender high on his left shin as the forward followed through on a lunging clearance just eight minutes into the game.
It would have no doubt been a sore sight for Antonio Conte, who was sitting in the Wembley stands - but fortunately for the Chelsea coach, Azpilicueta limped away following treatment and was able to complete the rest of the half for La Roja.
Vardy continued to be a thorn in Spain's side, as he went on to win the penalty with which Adam Lallana scored England's opener.
However, a number of Blues fans were dinstincly unimpressed on Twitter, with even broadcasters ITV Football suggesting it was an X-rated challenge.
