I disagree Colombia were the weakest side left in the tournament (Sweeden and Russia were/are). But can't disagree they were the dirtiest.
Back to the game. I was puzzled with Southgate's tactics. England started with 3-5-2 formation, but after they scored they parked the bus and played 5-3-2 and 5-4-1. Wtf? A totally wrong tactics. Southgate has so much attacking talent in his squad and he plays 3-5-2? I like this England team mostly because there are young players in it, and because the most of the players come from three most attacking and entertaining teams in England - Manchester City, Tottenham and Liverpool. These players don't defend, defending is not in their DNK, and they are used to win their games by playing great football. That's why Sterling, who is a free-scoring winger in the Premier League, looks like shit when he plays for the England national team. Manchester City play 4-3-3, Liverpool play 4-3-3, and Tottenham mostly 4-2-3-1, they are all attacking formations, and Southgate chooses 3-5-2? No surprise they didn't create any chances. They used Swansea tactics from last season.
